What heart sound may occur with angina?

• A. S3
• B. S4
• C. Opening snap
• D. Click

Answer: (B)

The presence of an S4 heart sound, also known as a "gallop," can often be heard in patients experiencing angina, particularly in the context of myocardial ischemia. The S4 sound is associated with a stiff or hypertrophied ventricle and is produced during atrial contraction when the atria push blood into the ventricle. This can occur in situations where the heart is under stress, such as during episodes of angina related to coronary artery disease. The development of the S4 sound indicates that the left ventricle is not filling adequately due to either increased stiffness or decreased compliance, which can be exacerbated during episodes of myocardial ischemia that occur with angina. This is different from other heart sounds; for instance, an S3 sound typically indicates congestive heart failure or volume overload, which is not specifically tied to angina. An opening snap is more commonly associated with mitral stenosis, while a click can be related to mitral valve prolapse or aortic stenosis, neither of which are directly linked to angina episodes.
