Final answer:
Mitral valve stenosis secondary to rheumatic heart disease often leads to pulmonary hypertension due to the increased pressure needed to move blood through the narrowed valve. Symptoms like angina pectoris and vetigo are not directly associated, while cyanosis may occur in severe cases.
Step-by-step explanation:
The signs and symptoms of mitral valve stenosis secondary to rheumatic heart disease originate from the effects of inflammation of the heart valves caused by an autoimmune reaction to Streptococcus pyogenes. This inflammation can lead to scarring and stiffness of the valve leaflets, hindering regular blood flow and leading to various clinical features. One of the prominent effects of mitral stenosis is pulmonary hypertension, caused by the increased pressure required to pump blood through the narrowed valve. This condition can lead to symptoms such as shortness of breath, fatigue, and in more severe cases, chest discomfort. While other valvular disorders might present with angina pectoris, in the setting of mitral stenosis, angina is not a direct symptom. Cyanosis occurs due to low oxygen in the blood and may be seen in severe cases. Vertigo is not commonly associated with mitral stenosis. Therefore, among the given options, pulmonary hypertension is the correct answer as it is commonly associated with mitral valve stenosis.
