Right Ventricle: The Overlooked Pump

We have spent a lot of time in the last several blogs on heart failure. Virtually all of these discussions have focused on left ventricular heart failure. What about right ventricular heart failure? Yes, the right ventricle (RV) can fail, too. But many of the most common cardiovascular problems—coronary heart disease, hypertension, valvular heart disease, atrial fibrillation—create dysfunction either exclusively or predominantly in the…

Cardiomyopathy: When the Heart Muscle is Sick

Cardiomyopathy: When the Heart Muscle is Sick

Over the last several weeks, we have been discussing the subject of CHF (congestive heart failure). I discussed the differences between heart failure from systolic dysfunction (problems with the heart contracting/pumping) and problems caused by diastolic dysfunction (problems during the relaxation phase of the cardiac cycle). These are clinical syndromes and are brought on by a variety of conditions, some of…

My Ankles Are Swollen—Does That Mean My Heart is Failing?!

My Ankles Are Swollen—Does That Mean My Heart is Failing?!

Hardly a day goes by that I am not asked that question by a patient. The causes of swollen ankles are numerous, but most people’s biggest fear is that they have CHF (congestive heart failure).  Indeed, peripheral edema (edema fluid causing swelling of the extremities, usually the legs) is often seen with CHF, and probably is its most visible manifestation. In that…

Women:  Listen to Your Heart

Women: Listen to Your Heart

Quick question:  What disease kills the most women every year? Strokes? Lung disease? Alzheimer’s?  Breast cancer?  Lung cancer? Nope, it’s heart disease—in fact, heart disease is more lethal to women than ALL cancers combined. And it kills three times more women each year than either lung disease, stroke or Alzheimer’s. So why do people think of heart disease as a “man’s illness?” There are several answers…

Mitral Regurgitation: A “Leaky Valve”

Mitral Regurgitation: A “Leaky Valve”

We turn this week to another valvular problem: mitral regurgitation. Unlike aortic stenosis, where the valve doesn’t open all the way, in mitral regurgitation (often abbreviated “MR”) the mitral valve (sitting between the left atrium and left ventricle) doesn’t close completely, allowing blood to regurgitate backward. Physicians usually describe this condition to their patients as having a “leaky valve.” The causes of…

High-Output Heart Failure: When High Isn’t Good Enough

High-Output Heart Failure: When High Isn’t Good Enough

We have touched on multiple aspects of CHF in several blogs this year, including discussions of how it occurs—whether in the setting of systolic dysfunction or diastolic dysfunction—what its manifestations are, how it is treated, and most recently a look at cardiomyopathies and how they cause CHF. All of these aspects of CHF have one thing in common—the heart isn’t doing…

Cardiomyopathy (Part III): When the Heart Muscle is Sick

Cardiomyopathy (Part III): When the Heart Muscle is Sick

In the last two blogs, we discussed what a cardiomyopathy is, paying particular attention to the categories of dilated and hypertrophic. This week we’ll complete our review of cardiomyopathies with a look at the restrictive category. While dilated and hypertrophic cardiomyopathies are defined by anatomic features (an enlarged heart chamber in the first and thickened ventricular walls in the second), restrictive…

Cardiomyopathy (Part II): When the Heart Muscle is Sick

Cardiomyopathy (Part II): When the Heart Muscle is Sick

Last time we discussed what a cardiomyopathy is, including the three categories of dilated, hypertrophic and restrictive. We then focused on types of dilated cardiomyopathies, along with some discussion about their treatment.  Today I’ll continue our review of cardiomyopathies by focusing on hypertrophic. Whereas a dilated cardiomyopathy is defined by the heart chamber being enlarged, a hypertrophic cardiomyopathy is defined by…

Cardiomyopathy: When the Heart Muscle is Sick

Cardiomyopathy: When the Heart Muscle is Sick

A few weeks ago, I devoted a couple blogs to the subject of CHF (congestive heart failure). At the time, I discussed the differences between heart failure from systolic dysfunction (problems with the heart contracting/pumping) and that caused by diastolic dysfunction (problems during the relaxation phase of the cardiac cycle). These are clinical syndromes and are brought on by a variety of…
