What Causes Heart Failure?

Generally, heart failure may be caused by factors such as excessive physical exertion, chronic sleep deprivation, hypertensive heart disease, coronary artery disease (CAD), or rheumatic heart disease. If any discomfort symptoms arise, it is advisable to seek timely evaluation and treatment at a reputable hospital. A detailed analysis follows:

1. Excessive Physical Exertion

Overworking the body places additional strain on the heart’s pumping function; prolonged high cardiac workload can lead to abnormal cardiac function. It is essential to balance work and rest appropriately, avoid strenuous physical activity, integrate rest with activity, and ensure adequate recovery time.

2. Chronic Sleep Deprivation

Prolonged insufficient sleep disrupts cardiovascular homeostasis, accelerates heart rate, increases cardiac load, and causes progressive myocardial damage. Establishing regular sleep habits—going to bed early and rising early—and avoiding chronic sleep deprivation are vital for maintaining normal cardiovascular function.

3. Hypertensive Heart Disease

Sustained elevated blood pressure increases resistance to ventricular ejection, leading to myocardial hypertrophy and myocardial strain, which may gradually progress to heart failure. Medications such as nifedipine sustained-release tablets, irbesartan tablets, and metoprolol tablets may be prescribed per physician guidance. Daily blood pressure monitoring and a low-salt, light diet are also recommended.

4. Coronary Artery Disease (CAD)

Narrowing of the coronary arteries compromises myocardial blood supply and oxygenation, resulting in myocardial cell injury or necrosis and impaired cardiac contractility and relaxation. Under medical supervision, medications such as enteric-coated aspirin tablets, atorvastatin calcium tablets, and isosorbide mononitrate tablets may be administered. In cases of severe coronary stenosis, percutaneous coronary intervention (PCI) with stent placement may be required.

5. Rheumatic Heart Disease

Rheumatic inflammation affecting cardiac valves leads to valvular stenosis or regurgitation, causing abnormal intracardiac blood flow and increasing cardiac workload—ultimately precipitating heart failure. Antibiotics such as benzathine penicillin, along with diuretics like furosemide tablets and spironolactone tablets, may be prescribed per physician instruction. Severe valvular dysfunction may necessitate surgical valve replacement.

In daily life, maintaining regular作息 (sleep-wake cycles), avoiding overexertion, strictly controlling blood pressure and lipid levels, undergoing routine cardiovascular screening, and seeking prompt medical attention for symptoms such as chest tightness or fatigue are all critical measures for preserving cardiac function.
