Is left ventricular dysfunction heart failure?
Heart failure is a significant public health concern in terms of prevalence, mortality rates, and economic burden. Left ventricular dysfunction or LV dysfunction of the heart is usually followed by congestive heart failure which ultimately leads to a multitude of cardiac disorders thereafter.
What causes left ventricular impairment?
Coronary artery narrowing or ischaemic heart disease is the dominant cause of heart failure and is often associated with acute or prior myocardial infarction. The remaining aetiologies include cardiomyopathy, hypertension, and a variety of other factors such as valve disease or myocarditis.
What is the ICD-9 code for stroke?
ICD-9-CM Diagnosis Code 434.91 : Cerebral artery occlusion, unspecified with cerebral infarction.
What is right ventricular failure?
Right ventricular (RV) failure occurs when the RV fails to maintain enough blood flow through the pulmonary circulation to achieve adequate left ventricular filling.
What is the difference between right and left-sided heart failure?
So when you have left-side heart failure, your heart can’t pump enough blood to your body. The right ventricle, or right chamber, moves “used” blood from your heart back to your lungs to be resupplied with oxygen. So when you have right-side heart failure, the right chamber has lost its ability to pump.
Is left ventricular systolic dysfunction the same as heart failure?
LVSD and heart failure are not synonymous. Some patients will suffer major left ventricular damage and yet be asymptomatic. Between 30–50% of patients who develop heart failure will do so in the absence of any LVSD, mitral regurgitation, or arrhythmias.
What happens to the right ventricle in heart failure?
The right ventricle then pumps the blood back out of the heart into the lungs to be replenished with oxygen. Right-sided or right ventricular (RV) heart failure usually occurs as a result of left-sided failure.
What is the ejection fraction of left ventricular failure?
Left ventricular failure can further subdivide into heart failure with preserved ejection fraction (HFpEF with EF over 50%), heart failure with reduced ejection fraction (HFrEF with EF less than 40%), or heart failure with mid-range ejection fraction (EF between 41 and 49 percent).

What are the risk factors for left ventricular failure?
The latter can cause left heart failure through left ventricular hypertrophy (leading to HFpEF), and also serves as a risk factor for coronary artery disease (which can lead to HFrEF). Diabetes, smoking, obesity, male gender, and a sedentary lifestyle are also considered risk factors.
What does it mean to have left sided heart failure?
Left-sided heart failure. Heart failure with preserved ejection fraction (HFpEF), also called diastolic failure (or diastolic dysfunction): The left ventricle loses its ability to relax normally (because the muscle has become stiff). The heart can’t properly fill with blood during the resting period between each beat.
