MPO reflects immune-cell oxidative activity that can accompany vascular injury, but it is a context marker—not a diagnosis. Here is how clinicians place it beside lipids, blood pressure, glucose, kidney function, and symptoms.
- What MPO measures: Myeloperoxidase is an enzyme released mainly by activated neutrophils and monocytes that can generate hypochlorous acid during immune activation.
- Assay-dependent range: A commonly used EDTA-plasma MPO assay classifies values below 350 pmol/L as lower risk, but laboratories use different methods and cutoffs.
- Not a heart-disease diagnosis: A high MPO result cannot show whether coronary arteries are narrowed, whether plaque is present, or whether chest pain is cardiac.
- MPO cardiac risk: MPO adds limited prognostic information in selected people, especially acute chest-pain cohorts, but does not replace LDL-C, ApoB, blood pressure, HbA1c, or smoking history.
- Troponin comes first: New chest pressure, breathlessness, sweating, fainting, or pain spreading to the jaw or arm requires urgent clinical assessment and ECG/troponin testing—not an MPO blood test.
- Marcadores de contexto: Non-HDL cholesterol, ApoB, lipoprotein(a), hs-CRP, eGFR, urine ACR, glucose, and blood pressure provide more actionable risk context.
- Common false context: Recent infection, autoimmune activity, smoking, kidney dysfunction, strenuous exercise, and acute tissue injury may raise myeloperoxidase levels.
- Próximo passo prático: Repeat an unexpected MPO result only when well and use the same laboratory and specimen type; do not start supplements or medication solely to lower MPO.
What an MPO Blood Test Actually Measures
A myeloperoxidase test measures an oxidative enzyme released by activated white cells; it reflects immune activity that can contribute to oxidation within vessel walls. It cannot diagnose coronary artery disease, predict an individual heart attack with certainty, or explain chest pain on its own. As of September 12, 2026, I use MPO only as a secondary clue beside established cardiovascular risk data.
Myeloperoxidase (MPO) is stored in neutrophils and monocytes and helps those cells make hypochlorous acid, a potent antimicrobial oxidant. In a vessel wall, the same chemistry can modify LDL particles, reduce nitric-oxide availability, and make plaque biology less stable; that is why MPO drew attention as a vascular-inflammation marker.
An MPO result is not interchangeable with a cholesterol result. A person may have LDL-C of 92 mg/dL and a temporarily high MPO after a respiratory illness, while another person with MPO in a lower range may still have high lifetime risk because ApoB is 145 mg/dL, blood pressure is 154/94 mmHg, and they smoke.
Kantesti AI é uma Analisador de teste de sangue de IA that reads specialized vascular markers alongside the standard results that change decisions most often, rather than treating one enzyme as a verdict. In my clinical work, the most useful question is rarely “Is MPO high?”; it is “What potentially modifiable risk is present with it?” Explore the wider guia de referência de biomarcadores for the tests commonly found on a cardiovascular panel.
Dr. Thomas Klein has seen patients become understandably alarmed by an MPO flag despite normal ECGs and reassuring symptom assessments. That anxiety is avoidable when the report states plainly that MPO describes a biological pathway, whereas imaging, symptoms, troponin, and conventional risk factors determine whether heart disease is likely.
The enzyme is not the antibody
MPO enzyme testing for vascular risk is different from an MPO-ANCA antibody test used in suspected vasculitis. One measures circulating enzyme concentration or activity; the other looks for an immune antibody and has an entirely different clinical purpose.
Why MPO Is Linked to Oxidative Stress in Arteries
MPO links to vascular risk because it can oxidize lipoproteins and impair nitric-oxide signalling within an inflamed arterial wall. The mechanism is biologically plausible, but plausibility does not make MPO a treatment target or a screening diagnosis.
MPO uses hydrogen peroxide and chloride to generate hypochlorous acid, often abbreviated HOCl. HOCl can chlorinate tyrosine residues on proteins and alter HDL and LDL function; these chemical footprints are measurable in research tissue studies, although a routine plasma value cannot locate where the oxidation occurred.
Atherosclerosis is not simply “rust in the arteries.” It involves ApoB-containing particles entering and being retained in the artery wall, local immune recruitment, endothelial dysfunction, and sometimes plaque rupture; an oxidized LDL result may be conceptually related but carries its own assay limitations.
The 2003 chest-pain study by Brennan et al. found that higher MPO identified greater near-term event risk even when initial troponin was negative (Brennan et al., 2003). That result was clinically interesting because MPO may rise before detectable myocardial cell injury, not because it proved that an infarction was underway.
One nuance often missed online: circulating MPO can originate from activated immune cells outside coronary arteries. Gum disease, an acute viral illness, inflammatory arthritis, chronic kidney disease, and tobacco exposure all provide alternative explanations, so the test has poor anatomical specificity.
When Clinicians May Consider Ordering MPO
Clinicians may consider an MPO blood test when conventional cardiovascular risk appears incomplete or when a specialist is refining risk in a patient with several borderline findings. Routine population screening is not supported by major prevention guidelines.
The test is sometimes ordered in preventive cardiology for a person with premature family history, metabolic risk, borderline traditional scores, or unexplained progression of vascular disease. It is less helpful in a 24-year-old with no symptoms, normal blood pressure, LDL-C of 68 mg/dL, and no major risk exposures because the pre-test likelihood of actionable disease is very low.
The evidence is honestly mixed on whether MPO materially improves decisions once modern risk assessment is complete. The 2019 ACC/AHA prevention guideline emphasizes pooled risk estimation, blood pressure, diabetes, smoking, cholesterol, coronary artery calcium in selected adults, and risk-enhancing factors such as Lp(a), rather than MPO as a routine test (Arnett et al., 2019).
Para muitos pacientes, hs-CRP is more familiar, but it answers a different question: it is a liver-derived acute-phase protein rather than a neutrophil enzyme. Read how symptoms and timing complicate high hs-CRP interpretation before assuming either marker identifies a diseased artery.
I usually reserve discussion of MPO for a follow-up visit, not a rushed annual check-up. A result that cannot alter LDL lowering, blood-pressure treatment, smoking cessation, diabetes care, or imaging decisions may add noise rather than useful precision.
MPO Cardiac Risk Testing Is Not an MPO-ANCA Test
An MPO cardiac-risk assay and an MPO-ANCA test are different laboratory investigations with different units, methods, and clinical consequences. A raised vascular MPO does not mean vasculitis, and a positive MPO-ANCA does not quantify cardiovascular oxidative stress.
MPO-ANCA detects antibodies directed against myeloperoxidase and is used with symptoms, urine findings, kidney function, imaging, and specialist assessment when small-vessel vasculitis is suspected. Coughing blood, rapidly worsening kidney function, purpura, neuropathy, or inflammatory eye disease warrant prompt medical evaluation; a cardiovascular MPO panel is not the appropriate work-up.
By contrast, MPO cardiac assays commonly report pmol/L, ng/mL, or assay-specific activity. ANCA laboratories often report antibody index units or U/mL with their own positivity threshold, which means a number from one report cannot be converted safely into a number from the other.
Kantesti é um serviço de interpretação de testes do laboratório de IA designed to separate similarly named tests by specimen, method, unit, and clinical question. This distinction matters particularly when patients upload several reports over years; see our guide to ANCA patterns and MPO for antibody-specific follow-up.
A laboratory flag is not a diagnosis. If an MPO-ANCA is positive, the estimated probability of vasculitis depends heavily on compatible symptoms and objective organ findings, while a lone low-positive result can occur in other autoimmune conditions, infections, and some medication exposures.
Why MPO Cannot Rule In or Rule Out a Heart Attack
MPO cannot rule in or rule out myocardial infarction because it does not measure heart-muscle injury and rises in many non-cardiac inflammatory states. Acute chest symptoms require an ECG, serial high-sensitivity troponin testing, vital signs, and clinician assessment.
High-sensitivity troponin reflects myocardial injury, though even troponin needs interpretation because kidney disease, tachyarrhythmia, myocarditis, and severe hypertension can elevate it. A changing value over 1 to 3 hours, symptoms, ECG findings, and local assay thresholds are more informative than a single MPO result.
In Brennan et al.’s 2003 New England Journal of Medicine cohort, MPO added prognostic information among patients presenting with chest pain, including some with initially negative troponin (Brennan et al., 2003). That does not justify using MPO at home or in primary care to exclude an emergency; the study population was already receiving urgent hospital assessment.
New pressure or tightness lasting more than 10 minutes, pain with exertion, fainting, severe shortness of breath, cold sweating, or pain spreading to the jaw, back, or arm should prompt emergency services. Our practical guia de exames de sangue para dor no peito explains why timing changes every cardiac marker.
A normal MPO is not a permission slip to ignore symptoms. Conversely, an elevated MPO without symptoms is usually a risk-discussion issue, not an emergency department diagnosis.
LDL and Non-HDL Cholesterol Provide Essential Context
LDL-C and non-HDL cholesterol provide essential context for MPO because atherosclerosis requires exposure to ApoB-containing lipoproteins, not oxidative stress alone. An elevated MPO with persistently low atherogenic cholesterol generally carries a different implication from the same MPO value with LDL-C of 190 mg/dL.
LDL-C de 190 mg/dL ou mais is considered severe hypercholesterolaemia in major guidelines and typically calls for active clinical treatment regardless of a calculated 10-year score. Non-HDL cholesterol equals total cholesterol minus HDL-C and captures LDL plus triglyceride-rich remnants; it is particularly useful when triglycerides exceed 175 mg/dL.
MPO may help describe a hostile vascular environment, but LDL and non-HDL show the particle cargo that can be retained in arterial tissue. In a patient with LDL-C 178 mg/dL and MPO 610 pmol/L on a validated assay, I would focus first on familial risk, ApoB, treatment options, adherence, and sometimes coronary artery calcium—not supplements marketed as antioxidants.
Kantesti AI highlights the pattern between lipid results and inflammatory context, including a high LDL that causes no symptoms. The absence of chest pain does not make LDL exposure harmless, and a high MPO does not identify which lipid intervention is right for an individual.
Statins lower LDL-C and reduce cardiovascular events, but a fall in MPO is not a validated treatment goal. Measurements should serve decisions that improve outcomes, not become a scoreboard for biochemical optimisation.
ApoB Often Explains Risk Better Than MPO Alone
ApoB often adds more actionable cardiovascular information than MPO because each atherogenic particle carries one ApoB molecule. A high ApoB identifies a high number of particles capable of entering artery walls, even when LDL-C looks only modestly raised.
ApoB is especially useful when triglycerides are high, insulin resistance is present, or LDL-C and non-HDL-C disagree. For example, LDL-C of 106 mg/dL with triglycerides of 260 mg/dL and ApoB of 125 mg/dL may indicate more atherogenic particles than LDL-C alone suggests.
The ACC/AHA guideline lists ApoB of 130 mg/dL ou mais as a risk-enhancing factor, particularly when triglycerides are persistently 200 mg/dL or more (Arnett et al., 2019). There is no comparable guideline threshold at which MPO alone mandates a statin, CT scan, or angiogram.
Esta é uma daquelas áreas em que o contexto importa mais do que o número. Nosso ApoB to ApoA1 ratio explainer shows why an apparently acceptable LDL value can conceal particle-related risk.
When I review a panel, an ApoB value that is consistently high across two fasting or non-fasting draws usually changes the conversation more than a one-off MPO result. The reason is simple: we have much stronger outcome-trial evidence for lowering atherogenic particle burden.
Lipoprotein(a) and Family History Change the Meaning of MPO
Lipoprotein(a), or Lp(a), and premature family history can elevate lifetime cardiovascular risk independently of MPO. A single Lp(a) measurement is usually reasonable in adulthood because levels are largely inherited and remain relatively stable.
Many guidelines consider Lp(a) at 50 mg/dL ou 125 nmol/L ou mais a risk-enhancing level, although mg/dL and nmol/L cannot be converted precisely because particle size varies. A parent, sibling, or child with myocardial infarction before age 55 in men or 65 in women is another signal that deserves formal review.
In the 2007 EPIC-Norfolk analysis, Meuwese and colleagues found higher MPO associated with future coronary disease among apparently healthy adults (Meuwese et al., 2007). That association does not tell us whether inherited Lp(a), lifelong ApoB exposure, hypertension, or smoking is the dominant risk driver for a particular person.
Patients sometimes assume a “normal cholesterol” report rules out inherited risk. It does not; our Lp(a) screening guide explains why Lp(a) can be clinically relevant even when LDL-C is 90 mg/dL.
MPO may modestly refine a discussion in a specialist setting, but it should not distract from documenting relatives’ ages at events, checking Lp(a), and investigating possible familial hypercholesterolaemia when LDL-C is very high.
Blood Pressure and Smoking Can Outweigh an MPO Result
Blood pressure and smoking status frequently influence cardiovascular risk more than MPO because both have proven causal links to heart attack, stroke, kidney disease, and premature death. A single office blood pressure of 140/90 mmHg needs confirmation, but persistent elevation deserves action regardless of MPO.
The usual diagnostic threshold for hypertension is office blood pressure of 140/90 mmHg ou mais in many settings, while home or ambulatory averages of 135/85 mmHg ou mais are commonly considered elevated. Guidelines vary by country and patient risk, but repeated properly measured readings matter far more than one anxious clinic measurement.
Smoking activates neutrophils, damages endothelium, and can elevate inflammatory markers, which makes an MPO result particularly difficult to interpret in a current smoker. Stopping tobacco lowers cardiovascular risk substantially even if a biomarker does not normalize immediately; no “detox” product substitutes for cessation support.
Kantesti can organize a cardiovascular report alongside results from a secondary-hypertension laboratory work-up, but an app cannot diagnose hypertension from a single reading. A validated home cuff, seated rest for 5 minutes, and a 7-day log are often more useful next steps.
I have seen a 47-year-old patient fixate on an MPO of 560 pmol/L while overlooking average home readings near 151/96 mmHg. Treating the established pressure problem was the priority; MPO did not alter that hierarchy.
Glucose, Kidney Function and Metabolic Risk Complete the Picture
Glucose status and kidney function are necessary context for MPO because diabetes and chronic kidney disease accelerate vascular risk through several pathways at once. HbA1c of 6.5% or higher can diagnose diabetes when confirmed appropriately, while eGFR below 60 mL/min/1.73 m² for 3 months indicates chronic kidney disease.
Diabetes increases atherosclerotic risk through glycation, altered lipoprotein metabolism, endothelial dysfunction, and renal injury. HbA1c of 5.7% a 6.4% indicates prediabetes, but anemia, recent transfusion, haemoglobin variants, and kidney disease can make HbA1c misleading; fructosamine testing is occasionally useful when that occurs.
Kidney disease can raise MPO because reduced clearance and chronic immune activation may coexist, while it independently raises cardiovascular risk. eGFR should be interpreted with urine albumin-creatinine ratio: an ACR of 30 mg/g ou mais is abnormal albuminuria and can change prevention priorities even with an eGFR above 60.
Metabolic syndrome is defined by a cluster of waist, triglycerides, HDL-C, blood pressure, and glucose abnormalities, not by MPO. Review the five measurable metabolic-syndrome criteria rather than relying on a vague “oxidative stress” label.
The practical issue is compounding risk. MPO of 500 pmol/L means more in a person with HbA1c 7.8%, ACR 120 mg/g, triglycerides 240 mg/dL, and hypertension than in a lean, normotensive person recovering from a cold.
Non-Cardiac Reasons Myeloperoxidase Levels Rise
Myeloperoxidase levels can rise with infection, autoimmune activity, smoking, chronic kidney disease, periodontal inflammation, acute tissue stress, and recent strenuous exercise. These causes make a single elevated MPO result nonspecific for coronary disease.
A febrile illness can change white-cell activation over days, whereas hs-CRP often peaks and falls on a different timetable. If a test was drawn during fever, after dental treatment, or within a few days of a severe workout, I would not use that MPO value to make a long-term cardiovascular judgment.
Intense endurance exercise can transiently change neutrophil counts, creatine kinase, CRP, and oxidative markers. A 52-year-old marathon runner with AST 89 IU/L after a race may also have a noisy inflammatory panel; the safer choice is recovery and repeat testing, as discussed in our guia de creatinina relacionada ao exercício.
Systemic autoimmune disease and vasculitis require their own clinical assessment rather than being reduced to an MPO cardiac score. Persistently high ESR or CRP plus rash, joint swelling, weight loss, nerve symptoms, abnormal urine, or fevers merits clinician review; ESR causes are broad.
A mildly elevated MPO after a cold is usually not an emergency. It is a reason to check whether the sample was timed sensibly and whether the conventional risk profile has been assessed.
MPO Reference Ranges Depend on the Assay and Specimen
MPO reference ranges depend on the laboratory method, calibration, and whether the sample is EDTA plasma or serum. A commonly cited EDTA-plasma classification uses below 350 pmol/L as lower risk and 540 pmol/L or higher as high, but these are not universal diagnostic boundaries.
Some reports use ng/mL, while others use pmol/L, and a conversion is not safe without knowing the assay calibrator and molecular form measured. Pre-analytical handling matters too: delayed processing, sample type, storage temperature, and cellular activation after collection can change measured concentrations.
The categories below are best viewed as one assay-family example, not as a universal normal range. A result of 420 pmol/L may be called intermediate on one EDTA-plasma report, but the same clinical sample may not have a directly comparable serum result from another laboratory.
Kantesti AI é uma plataforma de interpretação de biomarcadores por IA that preserves the laboratory’s own reference interval and flags unit mismatches when comparing historical reports. This is especially useful when testing crosses borders or laboratories; a true trend requires the same assay, same specimen, and similar health conditions.
If MPO is unexpectedly elevated, repeat it after at least 2 to 4 weeks without acute illness and after avoiding unusually strenuous exercise for 24 to 48 hours, unless your clinician has a reason to test sooner. Do not repeat indefinitely: two well-timed values usually answer whether the first result was transient.
A Sensible Follow-Up Plan for Elevated MPO
An elevated MPO result should trigger a structured cardiovascular review, not panic and not automatic medication. The first steps are confirming assay context, excluding recent inflammatory triggers, and measuring established modifiable risks.
Start with symptoms and urgency. Chest pressure, exertional breathlessness, syncope, new neurologic symptoms, or a markedly unwell state need real-time medical assessment; asymptomatic patients can usually arrange a non-urgent appointment to review risk over the next few weeks.
Then check the fundamentals: blood pressure averages, fasting or non-fasting lipid panel, non-HDL-C, ApoB when indicated, HbA1c or glucose, eGFR, urine ACR, smoking/vaping exposure, sleep, medications, and family history. A linha do tempo do exame de sangue helps identify whether illness, diet, or a medication change distorted the draw.
Kantesti AI can compare dates and help prepare questions for a clinician, while our exemplos de fluxos de trabalho clínicos show why results should be reviewed as patterns rather than isolated flags. It does not replace an ECG, imaging decision, physical examination, or individual prescribing advice.
Coronary artery calcium scanning can be useful for selected asymptomatic adults when a treatment decision remains uncertain after conventional assessment. It is not appropriate for everyone, and a high MPO alone is not a standard indication; age, calculated risk, radiation considerations, and the likely management consequence matter.
Can Lifestyle Changes Lower MPO and Cardiac Risk?
Lifestyle measures may reduce inflammatory burden and cardiovascular risk, but no guideline recommends treating a laboratory MPO target. The reliable goal is lowering causal risk factors: ApoB-containing lipoproteins, blood pressure, tobacco exposure, diabetes risk, inactivity, and poor sleep.
A Mediterranean-style dietary pattern, regular aerobic and resistance activity, adequate sleep, weight management when appropriate, and tobacco cessation improve risk factors with established outcome evidence. For triglycerides, reducing refined carbohydrates and alcohol exposure can matter substantially; see practical options for lowering triglycerides before retesting.
Antioxidant supplements have not earned a role as MPO-lowering cardiovascular therapy. High-dose vitamin E, beta-carotene, and mixed products can have harms or drug interactions, and a decline in a surrogate marker is not proof of fewer heart attacks or strokes.
The evidence for directly lowering MPO is not mature enough to prescribe around. If LDL-C falls from 170 to 85 mg/dL on a clinician-agreed plan, blood pressure falls from 148/92 to 126/78 mmHg, and smoking stops, I consider that a strong preventive success even if MPO has not been repeated.
Use trends sensibly: comparable lipid and blood-pressure trends are clinically stronger than frequent inflammatory-marker testing. Our guia de análise laboratorial longitudinal explains what to record before deciding that a biomarker has genuinely changed.
The Bottom Line: Put MPO in a Full Cardiovascular Assessment
MPO is a biologically meaningful oxidative-stress marker, but it cannot diagnose blocked arteries, exclude a heart attack, or replace established cardiovascular prevention tools. Its greatest limitation is nonspecificity: the same elevation can reflect vascular inflammation, infection, smoking, kidney disease, or another immune trigger.
A useful MPO discussion includes LDL-C or non-HDL-C, ApoB where relevant, Lp(a) at least once, blood-pressure averages, HbA1c or glucose, kidney function, urine albumin, smoking status, family history, symptoms, and medication history. A normal MPO does not cancel high ApoB or hypertension, and an elevated MPO does not prove plaque is present.
Dr. Thomas Klein’s practical rule is straightforward: test results should change a safe next action. If MPO does not alter prevention treatment, imaging, symptom triage, or the timing of a repeat assessment, it may be interesting but not clinically decisive.

Perguntas frequentes
O que significa um teste elevado de mieloperoxidase?
Um teste elevado de mieloperoxidase significa que há aumento da atividade circulante de células imunes que liberam MPO, o que pode acompanhar estresse oxidativo e inflamação vascular. Em um ensaio comum de plasma EDTA, valores de 540 pmol/L ou superiores se enquadram em uma categoria mais alta, mas o intervalo específico do laboratório sempre tem prioridade. Infecção, tabagismo, doença renal, atividade autoimune, inflamação gengival e exercício intenso recente também podem elevar o MPO. Um resultado alto não diagnostica doença arterial coronariana nem prova que um ataque cardíaco está ocorrendo.
Qual é um resultado normal no exame de sangue MPO?
Não existe um único resultado normal universal para o teste de MPO no sangue, pois os ensaios utilizam diferentes amostras, calibradores e unidades. Um ensaio comum em plasma de EDTA usa menos de 350 pmol/L como categoria inferior, 350 a 539 pmol/L como intermediário e 540 pmol/L ou superior como alto. Esses valores não devem ser aplicados a um resultado de MPO reportado em ng/mL ou a um ensaio sérico sem a faixa de referência própria do laboratório. Um MPO normal também não pode descartar LDL-C alto, ApoB alto, placa coronariana ou síndrome coronariana aguda.
O MPO pode diagnosticar doenças cardíacas?
Não, o MPO não pode diagnosticar doenças cardíacas porque não mostra estreitamento coronário, carga de placa, lesão do músculo cardíaco ou a causa dos sintomas torácicos. O diagnóstico de doença coronariana baseia-se em sintomas, exame, ECG, troponina de alta sensibilidade quando uma doença aguda é possível, avaliação de risco e, às vezes, imagem coronária ou teste de estresse. Na dor torácica aguda, medições seriadas de troponina em aproximadamente 1 a 3 horas são muito mais clinicamente acionáveis do que o MPO. O MPO pode adicionar informações secundárias de risco em cenários selecionados, mas não é um teste diagnóstico autônomo.
MPO é o mesmo que MPO-ANCA?
Não, o teste da enzima MPO e o teste MPO-ANCA respondem a perguntas diferentes. O teste cardíaco de MPO mede a concentração ou atividade circulante de mieloperoxidase, frequentemente em pmol/L, enquanto o teste MPO-ANCA mede anticorpos direcionados contra a MPO, frequentemente reportados em U/mL ou um índice de ensaio. O MPO-ANCA é usado na avaliação de possível vasculite de pequenos vasos em conjunto com sintomas, exames de urina, função renal, imagem e avaliação especializada. Um resultado elevado de MPO cardiovascular não significa que uma pessoa tenha vasculite.
Que exames devo verificar com um MPO elevado?
Um MPO elevado deve ser interpretado com pressão arterial, LDL-C, não-HDL-C, ApoB quando indicado, lipoproteína(a), HbA1c ou glicose, eGFR, relação albumina-creatinina na urina, exposição ao fumo, sintomas e histórico familiar. ApoB de 130 mg/dL ou superior e Lp(a) de 50 mg/dL ou 125 nmol/L ou superior são achados de risco aprimorado reconhecidos em estruturas de prevenção comuns. Se houver dor no peito, falta de ar intensa, desmaio ou sintomas neurológicos, ECG e teste de troponina de alta sensibilidade urgente têm prioridade. Repita o MPO apenas quando estiver bem e de preferência após 2 a 4 semanas, utilizando o mesmo laboratório e tipo de espécime.
Como posso baixar meu nível de mieloperoxidase?
There is no proven treatment target for lowering myeloperoxidase itself, so clinicians focus on changes that reduce cardiovascular events. These include stopping tobacco, controlling blood pressure, lowering LDL-C and ApoB when indicated, improving glucose control, exercising regularly, and following a sustainable dietary pattern. Avoid starting antioxidant supplements solely to change an MPO number because marker changes do not prove fewer heart attacks or strokes. A repeat result is most meaningful when measured with the same assay after recovery from illness and avoidance of unusually strenuous exercise for 24 to 48 hours.
