Your question: Does hypertension cause HFpEF or HFrEF?

In chronic HTN, which involves both pressure and volume overloads, the LV hypertrophy can be concentric or eccentric, and these types are associated with HF with a preserved ejection fraction (HFpEF) and HF with a reduced ejection fraction (HFrEF), respectively.

How does hypertension cause HFpEF?

Heart failure with preserved ejection fraction (HFpEF) is a prevalent but incompletely understood syndrome. Traditional models of HFpEF pathophysiology revolve around systemic HTN and other causes of increased left ventricular afterload leading to left ventricular hypertrophy (LVH) and diastolic dysfunction.

What causes HFpEF vs HFrEF?

HFpEF is preceded by chronic comorbidities, such as hypertension, type 2 diabetes mellitus (T2DM), obesity, and renal insufficiency, whereas HFrEF is often preceded by the acute or chronic loss of cardiomyocytes due to ischemia, a genetic mutation, myocarditis, or valvular disease [5,6].

What type of heart failure is caused by hypertension?

Hypertensive heart disease can lead to either diastolic heart failure, systolic failure, or a combination of the two. Such patients are at a higher risk for developing acute complications such as decompensated heart failure, acute coronary syndrome, or sudden cardiac death.

Does Pulmonary Hypertension Cause HFpEF?

Different clinical conditions associated with pulmonary hypertension–heart failure with preserved ejection fraction (PH-HFpEF). It is estimated that ≈50% of patients with HFpEF develop PH, and this may occur in the presence of different clinical conditions.

Can hypertension lead to HFrEF?

In chronic HTN, which involves both pressure and volume overloads, the LV hypertrophy can be concentric or eccentric, and these types are associated with HF with a preserved ejection fraction (HFpEF) and HF with a reduced ejection fraction (HFrEF), respectively.

How does hypertension affect afterload?

Systolic hypertension (HTN) (elevated blood pressure) increases the left ventricular (LV) afterload because the LV must work harder to eject blood into the aorta. This is because the aortic valve won’t open until the pressure generated in the left ventricle is higher than the elevated blood pressure in the aorta.

What causes preserved ejection fraction?

Heart failure with preserved ejection fraction (HFpEF) is a type of heart failure that occurs when the muscle in the left ventricle stiffens and is less able to relax, so the pressure inside the heart rises. HFpEF is usually caused by coronary artery disease, valvular heart disease, diabetes, obesity, or hypertension.

What type of heart failure is HFrEF?

Topic Overview. Heart failure with reduced ejection fraction (HFrEF) happens when the left side of your heart doesn’t pump blood out to the body as well as normal. It’s sometimes called systolic heart failure.

Is HFrEF systolic or diastolic?

In HF with reduced ejection fraction (HFrEF), also known as systolic HF, the heart muscle is not able to contract adequately and, therefore, expels less oxygen-rich blood into the body.

How does hypertension affect cardiac output?

In most forms of hypertension, the hypertensive state is maintained by an elevation in blood volume, which in turn increases cardiac output by the Frank-Starling relationship. Vasodilator drugs, which decrease systemic vascular resistance, are commonly used to treat hypertension.

How does hypertension cause ischemic heart disease?

High blood pressure can also cause ischemic heart disease. This means that the heart muscle isn’t getting enough blood. Ischemic heart disease is usually the result of atherosclerosis or hardening of the arteries (coronary artery disease), which impedes blood flow to the heart.

How does hypertension cause cardiomyopathy?

Persistent systemic hypertension induces LVH, fibrosis, diastolic dysfunction, and an increase in the activation of the RAAS, which leads to congestive heart failure[36,37]. One of the mechanisms of heart failure in patients with hypertension is LV diastolic dysfunction.

Does pulmonary hypertension cause diastolic heart failure?

The most common disease confused with pulmonary arterial hypertension is diastolic heart failure (also called heart failure with preserved ejection fraction-HeFPEF). In my practice about 70% of patients referred to me for PAH actually have diastolic heart failure.

What does HFpEF mean?

INTRODUCTION Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which patients have symptoms and signs of HF as the result of high ventricular filling pressure despite normal or near normal left ventricular ejection fraction (LVEF ≥50 percent) [1-5].

Can CHF cause pulmonary hypertension?

Pulmonary Hypertension Related to Left-Sided Heart Failure

Heart failure is not only a consequence of pulmonary hypertension, but it can also serve as underlying cause for the development of pulmonary hypertension.
