Introduction

Hypertension generally causes heart disease. It usually increases the cardiac workload, leading to hypertensive heart disease. It may also cause ventricular chamber enlargement, resulting in valvular insufficiency that induces heart disease. Additionally, it can affect the heart's electrophysiological function, causing arrhythmias that lead to heart disease. It may also promote atherosclerosis, triggering coronary atherosclerotic heart disease.

High blood pressure generally leads to heart disease, as it may cause myocardial cell degeneration, lead to blood regurgitation, and induce changes in myocardial tissue, among other effects. The specific reasons are as follows:

1. Causing myocardial cell degeneration

High blood pressure usually increases the workload on the heart. Over time, this may lead to myocardial tissue proliferation and hypertrophy, resulting in myocardial cell degeneration and ultimately causing hypertensive heart disease.

2. Causing blood regurgitation

Meanwhile, long-term high blood pressure may also cause enlargement of the ventricular chamber, leading to incomplete closure of heart valves (valvular insufficiency), which causes blood regurgitation and impairs normal cardiac function, thereby triggering heart disease.

3. Inducing changes in myocardial tissue

Additionally, persistent high blood pressure may alter myocardial tissue structure, affecting the heart's electrophysiological functions, subsequently causing arrhythmias and contributing to heart disease.

Moreover, high blood pressure often promotes atherosclerosis. Over time, this may result in blockage or narrowing of the coronary arteries, leading to coronary atherosclerotic heart disease. Strictly following medical advice to take antihypertensive medications such as nifedipine sustained-release tablets, captopril tablets, and nimodipine tablets, combined with lifestyle modifications to maintain blood pressure within the normal range, can significantly reduce the risk of developing heart disease.

What are the benefits of drinking hot water mixed with salt and sugar?

Under normal circumstances, dissolving salt and sugar in hot water for drinking offers various benefits, including replenishing fluids and electrolytes, rapidly restoring energy, relieving mild dehydration discomfort, reducing post-exercise fatigue, and alleviating symptoms of low blood sugar on an empty stomach. However, when consuming this mixture, one should pay attention to contraindications and precautions, control the amounts of salt and sugar used, avoid excessive intake, and particularly exercise caution if suffering from hypertension or diabetes.

Can I smoke while taking Pu'an Le tablets?

Smoking releases harmful substances such as nicotine, causing vasoconstriction and increased heart rate, which directly counteracts the effects of nifedipine controlled-release tablets in dilating blood vessels and lowering blood pressure. This makes it difficult to maintain stable blood pressure control, potentially leading to fluctuations and elevated blood pressure, thereby increasing the risk of hypertension-related complications. Meanwhile, these harmful substances damage vascular endothelium and accelerate the progression of atherosclerosis, completely opposing the goals of drug therapy.

Can patients with asthma use Metoprolol?

Metoprolol tartrate tablets, commonly known as Betaloc, may be cautiously used in patients with asthma who also have severe hypertension, coronary heart disease, or other conditions, if a physician's comprehensive evaluation indicates that the benefits outweigh the risks. Close monitoring is essential during treatment. Respiratory status should be continuously observed; if signs of asthma exacerbation occur, the drug must be discontinued immediately and emergency measures initiated.

Can mild pulmonary hypertension be cured?

In general, whether mild pulmonary hypertension can be cured depends on whether the underlying cause is clear and removable. Cases secondary to left heart disease or lung diseases often improve once the underlying cause is addressed; however, idiopathic pulmonary hypertension is difficult to cure completely and requires long-term management. Patients with mild pulmonary hypertension should avoid smoking and excessive alcohol consumption, refrain from strenuous exercise and high-altitude environments, and reduce stress on the lungs in daily life.
