How is HF diagnosed? While most patients with suspected HF do not require invasive testing for diagnosis, the clinical gold standard for diagnosis of HF is identification of an elevated pulmonary capillary wedge pressure at rest or exercise on an invasive hemodynamic exercise test in a patient with symptoms of HF.

Background. The morbidity and mortality from heart failure (HF) differ between patients with reduced (< 50%) and with preserved (≥ 50%) left ventricular ejection fraction (LV EF) on account of many factors, including abnormalities detected in the electrocardiogram (ECG).

Heart failure (HF) is a syndrome of ventricular dysfunction. Left ventricular failure causes shortness of breath and fatigue, and right ventricular failure causes peripheral and abdominal fluid accumulation; the ventricles can be involved together or separately.

What is the lowest ejection fraction you can live with?
If you have an EF of less than 35%, you have a greater risk of life-threatening irregular heartbeats that can cause sudden cardiac arrest/death. If your EF is below 35%, your doctor may talk to you about treatment with an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy (CRT).
What is normal ejection fraction for a 70 year old?

Is heart failure a death sentence?
Heart failure happens when the heart cannot pump enough blood and oxygen to support other organs in your body. Heart failure is a serious condition, but it does not mean that the heart has stopped beating.
