Introduction
Heart failure refers to the condition where the heart is unable to pump effectively. Patients with heart failure should generally avoid smoking. Cigarettes contain nicotine and tar, which are rapidly released into the bloodstream during smoking, impairing the function of vascular endothelial cells and reducing the heart's pumping capacity. Components in cigarette smoke also cause excessive activation of the sympathetic nervous system, increasing heart rate and oxygen consumption.
Heart failure refers to the condition in which the heart's ability to pump blood is impaired. Patients with heart failure should generally avoid smoking. The details are as follows:
Cigarettes contain nicotine and tar, which are rapidly released into the bloodstream during smoking. These substances impair endothelial cell function in blood vessels and reduce the heart's pumping capacity. Components in cigarette smoke also cause excessive activation of the sympathetic nervous system, increasing heart rate and oxygen consumption. Vasoconstriction increases both preload and afterload on the heart, further exacerbating heart failure. If patients with heart failure smoke heavily, it can adversely affect the heart, cerebral blood vessels, and lungs. It may also damage the mucous membranes of the respiratory tract, increase the risk of respiratory infections, and worsen heart failure. Therefore, smoking is generally not recommended for individuals with heart failure.
Patients with heart failure can receive treatment under a doctor's guidance using medications such as bisoprolol-amlodipine tablets or furosemide tablets. They may also engage in moderate physical activities such as jogging, hiking, or yoga to improve their immunity. Attention should be paid to dietary adjustments, avoiding spicy and greasy foods.
