What causes cardiac hypoxia?
Cardiac hypoxia may result from physiological factors such as a low-oxygen environment, or from pathological conditions such as diabetes or hypertension. The specific causes are analyzed as follows:
1. Physiological Causes
If one suddenly enters a high-altitude area, the surrounding low oxygen levels may lead to cardiac hypoxia. However, this is a normal physiological response and usually improves with timely oxygen supplementation or relocation to an environment with sufficient oxygen.
2. Pathological Causes
1) Diabetes
Prolonged uncontrolled blood glucose levels can damage the endothelium of coronary blood vessels, leading to atherosclerosis and insufficient blood supply to the heart, resulting in hypoxia. It is recommended to follow medical advice and use antidiabetic medications such as acarbose, gliclazide sustained-release tablets, or voglibose tablets for treatment.
2) Hypertension
Uncontrolled high blood pressure increases the workload on the heart, causing inadequate blood supply through the coronary arteries and leading to ischemia and hypoxia of myocardial cells. Under medical guidance, antihypertensive drugs such as labetalol hydrochloride tablets, furosemide tablets, or losartan potassium tablets may be used for treatment.
In addition, myocardial hypoxia may also occur in conditions such as myocarditis or coronary heart disease. It is essential to promptly treat the underlying disease according to medical advice.
