Study Notes
Cardiovascular System Lecture 15: When the Cardiovascular System Goes Wrong!
- The lecture covers common cardiovascular diseases and their treatment strategies.
- Specific diseases covered include hypertension, thrombosis & stroke, coronary heart disease & myocardial infarction, heart failure, valvular disease, and arrhythmias.
- The importance of cardiovascular disease affects 1 in 14 people globally, killing 1 in 3 worldwide.
- Ischaemic heart disease is the biggest cause of death in Europe, accounting for 45% of total mortality.
- Global risk factors for cardiovascular disease are high systolic blood pressure, dietary risks, high LDL cholesterol, high fasting plasma glucose, air pollution, high BMI, tobacco, and kidney dysfunction.
Objectives
- Students should be able to describe the pathophysiology and treatment strategies for common cardiovascular diseases.
- These diseases include hypertension, thrombosis & stroke, coronary heart disease & myocardial infarction, heart failure, valvular disease, and arrhythmias.
Content
- Importance of Cardiovascular Disease: The lecture begins with discussing the significance of cardiovascular diseases.
- How CVD affects Cardiovascular Function: This section analyzes how cardiovascular diseases affect the function of the cardiovascular system.
-
Vascular Disorders & Treatment: The treatment and pathologies of vascular disorders, including:
- Hypertension: A common condition, and a major risk factor for many health issues.
- Atherosclerosis: Characterized by plaque buildup in arteries.
- Thrombosis: Formation of blood clots in the circulatory system.
-
Cardiac Disorders & Treatment: The treatment and pathologies of cardiac disorders, including:
- Coronary Heart Disease & Myocardial Infarction: A severe condition with potential for fatality.
- Valvular Disease: Conditions affecting the heart valves.
- Heart Failure: An impairment in the heart's ability to pump efficiently.
- Arrhythmias: Irregular heartbeats.
Other Key Points
- Death rates in the UK from heart and circulatory diseases are declining.
- 4 out of 5 deaths from CVD have modifiable risk factors.
- Hypertension affects 15 million people in the UK and over 1 billion globally.
- Treatment strategies for cardiovascular diseases include medications, procedures, and lifestyle changes.
- Key causes for hypertension include genetic predisposition, high alcohol consumption, sedentary lifestyles, obesity, diabetes, and intrauterine environment.
- Hypertension can lead to conditions such as coronary artery disease, myocardial infarction, stroke, and chronic kidney disease.
- Treatment strategies for hypertension include thiazide diuretics, calcium-channel blockers, and angiotensin-converting enzyme inhibitors.
- Atherosclerosis is caused by endothelial damage and high LDL cholesterol. It leads to plaque formation, potentially causing stroke, coronary heart disease, and other complications.
- Statins are commonly used to treat atherosclerosis by inhibiting cholesterol synthesis.
- Thrombosis can result in stroke, myocardial infarction, and deep vein thrombosis (DVT). Treatment includes anticoagulants and anti-platelet therapy.
- Causes of heart failure range from hypertension and aortic stenosis to myocardial infarction.
- Treatments for heart failure include medications like beta-blockers, anti-hypertensives, as well as device/surgical treatments like mechanical heart pumps and cardiac transplants.
