Systolic Heart Failure

Depending on the part of the heart’s pumping cycle that’s been affected, heart failure can be of two types – diastolic and systolic. You can learn more about the symptoms, causes, treatment of diastolic dysfunction and differentiation from systolic dysfunction in our previous article.

Systolic heart failure occurs due to a problem in the heart’s contraction (or systolic) phase. It’s characterized by stretching and weakening of the left ventricular muscle, due to which the heart pumps out less oxygenated blood to the body.

It’s also known as heart failure with reduced ejection infraction. As the condition worsens, it can also weaken the right ventricle and take a toll on its pumping power too.

Causes Of Systolic Heart Failure

Hypertension (the left ventricle has to use increased pressure to pump blood through the body)

Coronary artery disease (buildup of cholesterol in the arteries) – with or without a heart attack.

Dilated cardiomyopathy (weakening of the left ventricle due to an infection or long-term exposure to alcohol and narcotics)

Abnormal heart rhythm (also known as atrial fibrillation)

Previous heart attack

Symptoms Of Systolic Heart Failure

Breathlessness – initially on exertion and in later stages even at rest or lying down. 

Swelling of feet, face, abdomen – due to fluid accumulation in various organs 

Engorged and pulsatile neck veins

Confusion (due to a lack of oxygen supply in the brain)

Weight gain (due to a buildup of excess fluid in the body)

Fatigue (due to reduced blood supply to the muscles)

Pale or bluish skin tone (due to restricted blood supply to the skin and other vital organs).
