Study Notes
Heart Attack - Causes, Diagnosis, Treatment
- Risk Factors: Age (men 45+, women 55+), high blood pressure, high cholesterol (LDL), high triglycerides, obesity, diabetes, lack of exercise, drug use (cocaine, amphetamines).
- Causes: Atherosclerosis (plaque buildup in arteries) is a major cause. Plaque rupture can lead to blood clots obstructing blood flow, causing a heart attack.
- Types of Heart Attacks: Myocardial Infarction Type 1 (plaque rupture/erosion with occlusive thrombus), Myocardial Infarction Type 2 (atherosclerosis and oxygen imbalance).
- Symptoms: Chest pain or discomfort (lasting more than a few minutes, potentially spreading to arms, neck, jaw, shoulders), shortness of breath, nausea, vomiting, anxiety, lightheadedness or fainting
- Complications: Arrhythmias (abnormal heart rhythms), heart failure, sudden cardiac arrest.
- Diagnosis: ECG (electrocardiogram), cardiac enzyme tests (blood tests to measure enzyme levels) angiography, stress test.
- Prevention: Maintain healthy lifestyle, manage risk factors like high blood pressure and cholesterol, and follow medical advice if needed.
- Treatment: Medications (aspirin, blood thinners, beta-blockers), angioplasty (balloon catheter to open blocked arteries), stents (small mesh tubes to keep arteries open). Coronary artery bypass graft (CABG).
- Coronary Artery Bypass Graft (CABG): A surgery to reroute blood flow around blocked coronary arteries.
- Causes of Heart Attacks-Preventable: Diabetes, Obesity, High cholesterol, High blood pressure, Smoking, Excessive stress.
- Causes of Heart Attacks-Unpreventable: Heredity, Menopause in women, Ethnicity, Age, Gender.
- Diagnosis Methods (Images): Angiograms, ECG
- Treatment Options (Images): Stents widening a narrowed artery, inserting a stent into a blocked artery.
Coronary Artery Anatomy
- Coronary anatomy: The diagram shows the coronary arteries branching off the aorta, providing blood to the heart muscle. Key coronary arteries illustrated are: RCA, LMCA, LAD, and LCx, along with associated branches to different heart sections.
- ECG lead relationships: The diagram shows the relationship of major coronary arteries with the standard ECG leads, demonstrating how ECG leads provide electrical signals from different parts of the heart.
