🫀 Understanding & Improving Ejection Fraction:
A Complete Guide
What is Ejection Fraction?
Ejection Fraction (EF) is the percentage of blood your heart pumps out with each contraction. Normal EF ranges from 55-70%. When this number drops, it can indicate heart muscle weakness.
Common Causes
Coronary artery disease
Previous heart attacks
High blood pressure
Valve disorders
Genetic factors
Diabetes complications
Chronic inflammation
Viral infections
Signs of Low EF
Fatigue
Shortness of breath
Swelling in legs
Reduced exercise tolerance
Irregular heartbeat
Dizziness
Sleep issues
***Ejection Fraction is fixable, your doctor typically follows a progressive approach, starting with medications like ACE inhibitors, beta blockers, and diuretics. When medications aren’t sufficient, doctors may recommend device interventions such as pacemakers or implantable cardioverter defibrillators, particularly when EF falls below 35%. These devices help coordinate heart rhythm and prevent sudden cardiac death.
For more severe cases, interventional procedures become necessary. These range from catheter-based treatments like angioplasty and stenting to surgical interventions such as coronary artery bypass grafting (CABG). In advanced cases where other treatments fail, doctors may consider a Left Ventricular Assist Device (LVAD) - a mechanical pump that supports heart function - or ultimately, heart transplantation. The choice of intervention depends heavily on factors like the patient's EF percentage, underlying cause of heart weakness, overall health status, age, and how well they've responded to previous treatments.
