Which is better, an ejection fraction of 70 or 60

Both an ejection fraction of 70 and 60 are within the normal range, and an ejection fraction of 60-70% usually indicates good cardiac contractile function. The clinical significance of ejection fraction needs to be evaluated comprehensively based on specific symptoms, cardiac structure, and other examinations. There is no absolute superiority or inferiority in numerical comparison alone. The ejection fraction of 70 represents the ability of the heart to pump 70% of the blood from the left ventricle during each contraction, which is a normal high value and is commonly seen in long-term exercise or physiological high dynamic states. These values may reflect higher cardiac efficiency, but if accompanied by symptoms such as palpitations and chest tightness, pathological factors such as hyperthyroidism or anemia need to be investigated. Regular aerobic exercise can be used in daily life to maintain cardiovascular function and avoid excessive intake of irritating substances such as caffeine. The ejection fraction of 60 is at the lower limit of the normal range and is commonly found in healthy middle-aged and elderly individuals or those with mild diastolic dysfunction. If the value is stable and there are no signs of post activity shortness of breath or lower limb edema, special intervention is usually not necessary. But regular monitoring of blood pressure and blood lipids is necessary to control cardiovascular risk factors. Patients with hypertension or diabetes should optimize basic disease management, and follow up with echocardiography when necessary.

It is recommended to undergo a physical examination including electrocardiogram and cardiac ultrasound once a year, and people over 40 years old can increase their exercise load test. Maintain a low salt and low-fat diet daily, accumulate 150 minutes of moderate intensity exercise per week, avoid smoking and excessive alcohol consumption. If symptoms such as persistent fatigue and intermittent nocturnal breathing difficulties occur, it is necessary to seek further evaluation from a cardiologist in a timely manner.
