LV systolic dysfunction was defined as an ejection fraction (EF) of less than 40% by echocardiography. The recovery of LV systolic function was defined as recovery of the EF to a level of 40% or greater and a net increase in EF of 10% or greater.
What is left ventricular systolic impairment?
Left ventricular systolic dysfunction (LVSD) is a common and serious complication of myocardial infarction (MI) that leads to greatly increased risks of sudden death and of heart failure. Effective and cost effective treatment is available for such patients that can reduce both morbidity and mortality.
What is the treatment for left ventricular systolic dysfunction?
Left ventricular systolic dysfunction is common postoperatively and is treated with optimization of preload, maintenance of a high normal heart rate (e.g., with pacing at 90/min), and inotropic support (see Chapter 21). Echocardiography and a pulmonary artery catheter are helpful to guide therapy.
What are the most common causes of left ventricular systolic dysfunction?
Left ventricular systolic dysfunction is the most common cause of cardiogenic pulmonary edema. This dysfunction can be the result of coronary artery disease, hypertension, valvular heart disease, cardiomyopathy, toxins, endocrinologic or metabolic causes, or infections.
What does left ventricular systolic function mean?
A normal left ventricular ejection fraction (LVEF) ranges from 55% to 70%. An LVEF of 65%, for example, means that 65% of the total amount of blood in the left ventricle is pumped out with each heartbeat. Your EF can go up and down, based on your heart condition and how well your treatment works.
How long can you live with left ventricular systolic dysfunction?
Generally, 50% of patients with left ventricular dysfunction go one to live beyond 5 years after being diagnosed.
Can left ventricular failure be cured?
For most people, heart failure is a long-term condition that can’t be cured. But treatment can help keep the symptoms under control, possibly for many years. The main treatments are: healthy lifestyle changes.
Is systolic dysfunction the same as heart failure?
In general, heart failure is a condition that occurs when your heart isn’t pumping efficiently enough to keep you healthy. Your heart may pump even less efficiently when you’re doing physical activity or feeling stressed. If you have systolic heart failure, it means your heart isn’t contracting well during heartbeats.
What happens if left ventricle not working properly?
When the left ventricle fails, increased fluid pressure is, in effect, transferred back through the lungs, ultimately damaging the heart’s right side. When the right side loses pumping power, blood backs up in the body’s veins.
Can a damaged left ventricle be repaired?
Left ventricular reconstructive surgery (or aneurysm repair surgery) allows the surgeon to remove the scarred, dead area of heart tissue and/or the aneurysm and return the left ventricle to a more normal shape.
