Question

Which of the following statements is not true?
A. A heart murmur usually indicates a fatal heart defect
B. Angina pectoris may occur when doing strenuous activity after eating a heavy meal
C. An incompetent valve can permit backflow of blood
D. A coronary artery spasm can obstruct blood flow

Answer 1

The human heart is one of the most vital organs in the body, as it is responsible for keeping us alive. It's a four-chambered muscular organ. The heart is approximately the size of a clenched hand. The human heart is one of the most powerful and hardest-working muscles in the body, and it works throughout a person's life.

Complete answer:
Coronary heart disease, heart attacks, congestive heart failure, and congenital heart disease are the top causes of mortality in both men and women.
Option A: A heart murmur usually indicates a fatal heart defect: Heart murmurs can be benign (innocent) or dangerous (abnormal). A harmless heart murmur does not indicate the presence of heart disease and does not require treatment. Follow-up testing is required to establish the source of abnormal heart murmurs. The treatment focuses on the source of your abnormal heart murmur. So, this is not a true statement.
Option B: Angina pectoris may occur when doing strenuous activity after eating a heavy meal: Angina is more likely to occur with physical exercise, mental stress, or exposure to cold conditions, as well as after a large meal. So, this is a true statement.
Option C: An incompetent valve can permit backflow of blood: Insufficiency or incompetence are other terms for regurgitation. Regurgitation occurs when a valve fails to shut correctly, allowing blood to seep backward instead of flowing in a one-way flow. Only a tiny amount of blood can go forward to your body's organs if too much blood travels backward. So, this is a true statement.
Option D: A coronary artery spasm can obstruct blood flow: This transient tightening of arterial wall muscles can reduce or even halt blood flow to a portion of the heart muscle. The most prevalent cause of myocardial ischemia is coronary artery spasm. So, this is a true statement.

Thus, the correct answer is option A: A heart murmur usually indicates a fatal heart defect.

Note:
Early detection of heart disease makes it simpler to treat, so talk to your doctor about any concerns you have about your heart health. If you're worried about getting heart disease, talk to your doctor about what actions you may take to lower your risk. If you have a family history of heart disease, this is very essential.
