Signs to recognize left heart failure – VnExpress


Patients easily gain weight, leg edema, chest tightness, fatigue, often wake up at night because of difficulty breathing.

The heart has two main pumping chambers: the right ventricle and the left ventricle. The right ventricle carries blood to the lungs, taking in oxygen. The left ventricle is larger and has the function of pumping oxygen-rich blood to the body. Left-sided heart failure is a condition in which the heart loses its ability to pump blood, causing the organs in the body not to receive enough oxygen.

People who are obese and have coronary heart disease are prone to left heart failure because this part has to work too hard to pump blood. About 15% of people die within the first year after being diagnosed with the disease. This rate increases to 50% for patients who have been treated for 5 years. People over the age of 65 are at increased risk for heart failure.

According to experts, reduced function of the left ventricle is a common cause of left heart failure with two main types. Heart failure with preserved ejection fraction (diastolic heart failure): the heart muscle contracts normally, but the left ventricle does not pump enough blood. Heart failure with reduced ejection fraction (systolic heart failure): The heart muscle does not contract effectively, the amount of oxygen-rich blood pumped into the body decreases.

The symptoms of left-sided heart failure can be easily confused with allergies, stuffy nose, indigestion or a cold, making it difficult to recognize. When the heart fails, fluid backs up into the lungs and around the heart.

Elderly, obese people may present with symptoms of left heart failure such as chest tightness, fatigue, shortness of breath when exerted or lying down, paroxysmal nocturnal dyspnea, tachycardia, edema of the feet and ankles. , weight gain, nausea, persistent cough, wheezing, increased urination. If not diagnosed and treated promptly, the patient’s heart will be overloaded, leading to an enlarged heart muscle (enlarged heart), tachycardia, high blood pressure, less blood flow to the hands and feet. even cause kidney damage, liver, heart attack.

Left-sided heart failure has the following causes:

HypertensionChronic high blood pressure is a common cause of diastolic heart failure, which makes the heart work harder to pump blood. As a result, the heart muscle becomes stiff, affecting the heart rate.

Diabetes: High blood sugar can cause hardening of the blood vessels, forcing the heart to work continuously.

Coronary artery disease: Very low blood flow to the heart can cause ischemia that causes the heart muscle cells to stop working.

Pericarditis: limits the heart’s ability to hold blood.

Fat: Being overweight increases the fat layer around the heart.

Sedentary: Not exercising regularly is a potential risk factor for high blood pressure, diabetes, coronary heart disease, and obesity.

Sleep apnea: This condition causes the body to have many complicated changes, prone to high blood pressure, reduced oxygen supply to the heart, increased activity of the nervous system. These changes cause a mismatch between oxygen supply and demand. When this happens, you are at increased risk for systolic and diastolic heart failure as well as other heart conditions.

Systolic dysfunction: Due to idiopathic dilated cardiomyopathy, coronary (ischemic) disease, high blood pressure, heart valve disease. People with diastolic dysfunction often have high blood pressure, obesity, diabetes, atrial fibrillation, and high cholesterol.

Currently, patients with left heart failure are treated depending on the condition and type of disease. The disease can be treated with many drugs including ACE inhibitors, beta blockers, antibiotics, diuretics… Finding the main cause of the disease will prevent heart failure from progressing. In addition, patients need to follow a nutritious diet, eat less salt, do not drink alcohol, beer, smoke, create a healthy lifestyle, exercise.
