Introduction

This video lecture discusses complications related to atherosclerosis and coronary artery disease (CAD). It covers the various acute and chronic consequences of atherosclerosis, including thromboembolic events, myocardial ischemia, and the impact of various factors on myocardial oxygen supply and demand. The lecture also highlights the significant mortality rate associated with heart disease and the ongoing challenge of managing this condition.

Key Takeaways

• Atherosclerosis Complications: Atherosclerosis can lead to several complications, including hemorrhage, vessel rupture, aneurysm formation, thromboembolic events (heart attacks, strokes), and ischemia.
• Myocardial Oxygen Imbalance: CAD is characterized by an imbalance between myocardial oxygen supply and demand. Factors affecting supply include oxygen content, coronary blood flow, and perfusion pressure. Factors affecting demand include wall stress (ventricular pressure, radius, wall thickness), heart contractility, and heart rate.
• Risk Factors for CAD: Hereditary factors, age, and even emotional factors contribute to the risk of CAD. Conversely, cardiovascular disease can also contribute to depression and other mental health issues.
• High Mortality Rate: Heart disease remains a leading cause of death, with a significant number of heart attacks and deaths occurring frequently in the United States.
• Treatment Advances: While advancements in medications and interventions have improved treatment, heart disease continues to be a major public health concern.
