Study Notes
Myocardial Oxygen Demand
- Relationship between Myocardial Oxygen Demand and Muscle Mass: More muscle mass requires a higher oxygen demand.
Ischemic Heart Disease (IHD)
- Common Treatment for IHD with Low Hemoglobin: Blood transfusion is often used when hemoglobin levels fall below 9-10 g/dL.
- Alternative Name for IHD: Coronary artery disease (CAD)
- Characteristics of Cardiac Pain: Heavy, tight, or pressure-like sensation.
- Symptomatic IHD: Characterized by chest discomfort due to angina pectoris.
-
Risk Factors for CAD: Multiple factors contribute to the development of CAD, including:
- High blood pressure
- Diabetes
- High cholesterol
- Smoking
- Family history
- Physical inactivity
Angina Pectoris
- Duration: Angina pectoris typically lasts 2 to 30 minutes.
Resting ECG
- Recommended State for Recording a Resting ECG: Patients suspected of having IHD should be recorded in the resting state for accurate interpretation.
Asymtpomatic Ischemia
- Population with Frequent Asymptomatic Ischemia: Patients with diabetes are often observed to have silent ischemia due to neuropathy.
Vasospasm Triggers
- Non-Triggering Factor: High blood pressure does not trigger vasospasm.
Saturated Fat Intake
- Recommended Intake: According to ACC/AHA guidelines, limit saturated fat intake as part of a healthy diet.
Heart Perfusion
- Diastolic Perfusion: The heart is the only organ that receives blood flow during diastole (relaxation phase).
