"How is medication administered for left heart failure-induced pulmonary edema?"

Treatment for Left Heart Failure and Pulmonary Edema

Patients with left heart failure and pulmonary edema require diuretics, cardiac stimulants, and vasodilators as prescribed by their physicians. If symptoms are severe, supplemental oxygen therapy may also be necessary for improvement. Here's an overview of the medications involved:

1. Diuretics

1.1 Furosemide Tablets: A potassium-excreting diuretic that rapidly eliminates excess water from the body, thereby alleviating symptoms.

1.2 Hydrochlorothiazide Tablets: Reduces heart load and eliminates water and sodium retention, also improving discomfort caused by the disease.

2. Cardiac Stimulants

2.1 Digoxin Tablets: A digitalis glycoside that enhances myocardial contractility and reduces ventricular rate. It can be used under medical supervision for呼吸困难 caused by the disease.

2.2 Propranolol Hydrochloride Sustained-Release Capsules: Slows heart rate and inhibits myocardial contractility, helping to manage elevated heart rates and accompanying chest tightness.

3. Vasodilators

3.1 Isosorbide Dinitrate Tablets: Relaxes vascular smooth muscle, dilating both arterial and venous walls. This medication can significantly lower blood pressure in patients with the condition.

3.2 Metoprolol Tartrate Sustained-Release Tablets: Reduces myocardial oxygen consumption, benefiting patients experiencing palpitations, shortness of breath, and other discomforts.

4. Oxygen Therapy

In daily life, patients are advised to rest adequately, maintain good air circulation in their rooms, and follow a healthy diet consisting of light, easily digestible foods like rice porridge and pumpkin porridge. Spicy, cold, or raw foods are discouraged as they may hinder recovery.
