    Study Notes

    IHD Risk Factors

    • Age: > 45 years for males, > 55 years for females
    • Family history: premature IHD in males < 55 years, females < 65 years
    • Hypertension: BP > 130/80 or on anti-hypertensive therapy
    • Smoking
    • Hyperlipidemia: HDL < 40 mg/dL (subtract one risk factor if > 60 mg/dL)
    • Diabetes
    • Obesity: BMI > 30 kg/m2
    • Sedentary lifestyle
    • CVD (cardiovascular disease)
    • PAD (peripheral arterial disease)

    IHD Symptoms

    • Typical pain: pressure, heaviness, or squeezing in the anterior chest area
    • May radiate to the neck, jaw, shoulder, back, or arm
    • May be accompanied by dyspnea, nausea, vomiting, or diaphoresis
    • Sharp pain is not a typical symptom of IHD
    • Symptoms of stable angina are often provoked by exertion, emotional stress, exposure to cold temperatures, and heavy meals
    • Symptoms of stable angina are relieved within minutes by rest or sublingual nitroglycerin
    • Symptoms of ACS: pain occurs at rest (without provocation) and is prolonged and unrelieved by sublingual nitroglycerin

    Diagnosis and Evaluation

    • A thorough medical history, physical exam, and laboratory analysis are necessary to ascertain cardiovascular risk factors
    • Laboratory analyses should assess for glycemic control, fasting lipids, hemoglobin, and organ function
    • Electrocardiogram (ECG): a 12-lead ECG recorded during rest is often normal in patients with chronic stable angina
    • Cardiac troponins T and I are the preferred markers for myocardial injury
    • Serum troponin levels increase within 3-12 hours from the onset of chest pain, peak at 24-48 hours, and return to baseline over 5-14 days
    • CK-MB levels increase within 3-12 hours of onset of chest pain, reach peak values within 24 hours, and return to baseline after 48-72 hours

    Angina Types

    • Stable Angina (also known as "effort angina")
    • Unstable Angina
    • Prinzmetal's (Variant) Angina
    • Chronic Stable Angina (CSA): also known as "effort angina", refers to the classic type of angina related to myocardial ischemia
    • Symptoms of CSA typically decline several minutes after activity and happen again when activity resumes
    • Other recognized precipitants of stable angina include cold weather, heavy meals, and emotional stress
