Heart failure can be relieved by changing the body position. Even a small change in lung volume can cause impairment of right ventricular systolic function caused by increased pulmonary vascular resistance, thus affecting hemodynamics and being able to reduce the cardiac load of heart failure! Method 1: When the body is semi-recumbent, the blood in the lower extremities and abdomen tends to stagnate due to gravity, which reduces the amount and pressure of blood flowing into the heart, known as reducing the preload of the heart. Rest can avoid paroxysmal cardiogenic dyspnea in the evening. Method 2: Control of blood pressure in those with hypertension is an important measure to protect the heart. When blood pressure rises, the resistance of the heart to ejection of blood into the aorta increases, which is medically known as increased afterload. Over time, this is bound to cause cardiac hypertrophy and heart enlargement. Method 3: The sodium ion in salt has the effect of increasing blood volume, the increase in blood volume will increase the burden on the heart, this increased burden of eating more sodium and salt can last for hours, if every meal are eating a high salt diet, it will increase the burden on the heart for a long time. Method 4: Avoid fatty meat and other greasy foods, and eat less sweets. Daily meals with lean meat and beans with each meal eaten with eight, nine minutes full can be. Excessive intake of food, water and other beverages will rapidly increase blood volume, thus increasing the burden on the heart of heart failure patients. Method 5: There is a relationship between human emotions and the occurrence of heart disease. They point out that people who have high mood swings and are easily agitated have about six times higher incidence of heart disease than people who are calm in situations. Therefore, heart failure patients should maintain emotional stability.
