- Block calcium channels in blood vessels
Correct answer: Reduce heart rate and myocardial contractility
Beta-blockers exert their therapeutic effects by blocking beta-adrenergic receptors, primarily beta-1 receptors in the heart. This blockade leads to a reduction in heart rate, decreased myocardial contractility (the force of heart muscle contraction), and consequently, a decrease in cardiac output and blood pressure. They are used to treat conditions like hypertension, angina, and arrhythmias by reducing the heart's workload.
Question 87: In heart failure with reduced ejection fraction (HFrEF), which compensatory mechanism initially maintains cardiac output but ultimately worsens the condition?
- Reduced sympathetic tone
- Decreased heart rate
- Activation of the renin-angiotensin-aldosterone system (RAAS) (Correct answer)
- Decreased preload
Correct answer: Activation of the renin-angiotensin-aldosterone system (RAAS)
RAAS activation causes sodium and water retention increasing preload and afterload, which provides short-term compensation but leads to long-term cardiac remodeling and deterioration.
Question 88: In peptic ulcer disease, how does H. pylori infection contribute to mucosal injury?
