Introduction
Ejection fraction is a measure of the percentage of blood pumped out of the left ventricle with each heartbeat relative to the total amount of blood filling the left ventricle. Generally, a low ejection fraction may lead to low blood pressure, but not always. Patients are advised to seek timely medical attention when experiencing discomfort and to undergo standardized treatment under a doctor's guidance, which can help promote recovery.

  Ejection fraction refers to the percentage of blood pumped out of the left ventricle with each heartbeat relative to the total volume of blood filling the left ventricle. Generally, a low ejection fraction may lead to low blood pressure, but not always. Specific details are as follows:

  1. Yes

  Poor cardiac pumping ability may result in low blood pressure. A reduced ejection fraction is often caused by decreased cardiac output and commonly occurs in conditions such as enlarged heart, myocarditis, or acute myocardial infarction, all of which impair the heart's contractile function. Patients can take medications such as metoprolol succinate extended-release tablets or spironolactone capsules under medical supervision to alleviate symptoms, or undergo surgical treatment at a qualified hospital.

  2. No

  Some patients with hypertension may maintain normal or even high blood pressure despite having a reduced ejection fraction. Hypertension can cause thickening of the left ventricular wall, enabling the heart to sustain higher blood pressure. Even if ejection fraction declines before heart failure progresses severely, relatively normal blood pressure may still be maintained.

  It is recommended that patients seek timely medical attention and follow standardized treatment under a doctor’s guidance when experiencing discomfort, which helps promote recovery.
