What does it mean when the murmur of hypertrophic cardiomyopathy increases?
The enhancement of murmurs in hypertrophic cardiomyopathy may result from normal physiological causes, or it may be due to pathological conditions such as hypertrophic obstructive cardiomyopathy or chromosomal abnormalities. The specific analysis is as follows:
I. Normal Physiological Causes
During intense physical activity or excessive fatigue, the heart's contractility increases and contraction rate accelerates. This heightened cardiac activity can lead to an increase in heart murmurs.
II. Pathological Causes
1. Hypertrophic Obstructive Cardiomyopathy
When there is asymmetric thickening of the heart muscle, it can cause obstruction in the outflow tract, leading to hypertrophic obstructive cardiomyopathy, which produces murmurs characteristic of hypertrophic cardiomyopathy. The murmur may become louder when there is a reduced volume of blood returning to the heart.
2. Chromosomal Abnormalities
Congenital chromosomal abnormalities may cause mitral valve insufficiency, resulting in enhanced murmurs associated with hypertrophic cardiomyopathy. This may be accompanied by symptoms such as dyspnea and chest tightness.
Patients experiencing increased murmurs related to hypertrophic cardiomyopathy are advised to seek timely medical evaluation. Under a doctor's guidance, medications such as digoxin tablets or deslanoside injection may be used for treatment.
