Introduction
一般情况下，左室射血分数指的是左心室射血分数，左心室射血分数67%无并发症正常，但如果有并发症则不正常。如果Patient出现不适Symptoms，Recommendation及时前往医院就诊，以免耽误病情。生活中一定要注意饮食和作息情况，以免导致不适Symptoms加重。
Generally, left ventricular ejection fraction (LVEF) refers to the percentage of blood ejected from the left ventricle with each heartbeat. An LVEF of 67% is considered normal in individuals without complications; however, it may be considered abnormal if complications are present. If a patient experiences discomfort or symptoms, prompt medical evaluation at a hospital is recommended to avoid delays in diagnosis and treatment. The detailed analysis is as follows:
1. Normal
Left ventricular ejection fraction represents the ratio of stroke volume to end-diastolic volume in the left ventricle and is an important indicator for assessing left ventricular systolic function. The normal range for LVEF is 50%–70%. A value of 67% falls well within this normal range.
2. Abnormal
Although an LVEF of 67% is within the normal range, the presence of comorbidities such as hypertension or hypertrophic cardiomyopathy cannot rule out the possibility of heart failure. If patients experience clinical symptoms such as chest tightness, shortness of breath, or difficulty breathing, they should seek medical attention promptly, undergo appropriate diagnostic tests, and receive targeted treatment based on a confirmed diagnosis. Therefore, an LVEF of 67% alone is insufficient for a definitive diagnosis, and patients should follow medical advice to complete further evaluations at a reputable healthcare facility.
In daily life, attention should be paid to diet and sleep patterns to prevent worsening of symptoms.
