Stable angina only

Normal cardiac function

Which of the following is a primary symptom of unstable angina?

Chest pain only during physical exertion

Persistent chest pain that lasts longer than 15 minutes (correct)

No chest pain, only shortness of breath

Describe the pathophysiology of angina pectoris and its primary symptoms.

Angina pectoris is caused by reduced blood flow to the heart muscle, leading to chest pain. Symptoms typically include discomfort in the chest, which may radiate to the arms, neck, or jaw, often triggered by physical exertion or stress. Signup and view all the answers

What is the difference between essential and secondary hypertension?

Essential hypertension has no identifiable cause and accounts for the majority of cases, while secondary hypertension is due to a specific underlying condition, such as kidney disease. Signup and view all the answers

What are the common adverse effects associated with diuretics used in hypertension treatment?

Common adverse effects of diuretics include electrolyte imbalances, dehydration, and increased urination. They can also lead to dizziness and hypotension in some patients. Signup and view all the answers

Identify the potential complications of untreated hypertension.

Untreated hypertension can lead to serious complications such as heart failure, stroke, kidney damage, and vision loss. These conditions stem from the chronic strain high blood pressure places on blood vessels and organs. Signup and view all the answers

Explain what a hypertensive emergency is and how it differs from hypertensive urgency.

A hypertensive emergency involves severely elevated blood pressure that leads to acute organ damage, while hypertensive urgency has high blood pressure without immediate organ damage. Both require immediate medical attention. Signup and view all the answers
