Heart failure: It’s not what you think
Heart failure is more prevalent in the South. Here’s what you need to know.
Those stubborn pounds you’ve been meaning to lose. Those daily walks you’ve been meaning to start taking. Oh yeah, and a checkup, yes, that’s on the to-do list, too.
This isn’t a guilt list. We all get busy and just, well, don’t do the good we ought to do.
This is our Why List.
About 900,000 people are diagnosed with heart failure each year in the United States. And, you guessed it, it’s more prevalent in the South.
Nationally, about 6 million people are living with heart failure.
What is heart failure?
“Heart failure is an epidemic,” said Vanderbilt Heart’s Kelly Schlendorf, M.D., a heart failure cardiologist. “It affects people of all backgrounds across the U.S., and it’s often under-recognized and poorly understood, even by individuals who carry the diagnosis.
“To some, ‘heart failure’ implies that the heart has stopped beating. But this definition isn’t accurate.”
Instead, heart failure refers to a condition in which a person’s heart muscle is weakened, unable to pump blood to the body in the way that it should, resulting in symptoms like shortness of breath, fatigue and fluid buildup in the legs and feet.
It’s a chronic disease and must be treated with medications, diet and lifestyle changes for the rest of a patient’s life. Fewer than 50 percent of people diagnosed with heart failure are still living after 5 years.
Risk factors for heart failure
Common risk factors for heart failure include coronary artery disease, high blood pressure, diabetes and obesity. At least half of people diagnosed with heart failure have one or more of these risk factors, Schlendorf said.
“It’s important for patients to recognize what the risk factors are,” Schlendorf said. “A person with high blood pressure may feel just fine, and choose not to take his or her blood pressure medications. However, uncontrolled blood pressure over many years can ultimately lead to heart failure.”
For other patients with heart failure, causes may include things like genetics, viral infections, excessive alcohol use and certain chemotherapies. For many patients, the cause of their heart failure is not known.
Heart failure prevalence is higher in the 65-and-older population.
“But, old age is not synonymous with heart failure,” Schlendorf said.
Tips for reducing your chances of developing heart failure? “It’s nothing special or complicated,” she advised. “Lead a healthy lifestyle. See your doctor. Work to control your diabetes or high blood pressure. Stay active.”
Salt and heart failure
“Plenty of data suggests that higher sodium intake is associated with higher blood pressure,” she said. “Especially for patients who already have high blood pressure, limiting salt in the diet is important in helping to reduce one’s chances of developing heart failure.”
For patients who already carry a diagnosis of heart failure, however, the impact of a sodium-restricted diet is less clear.
Schlendorf treats patients in advanced stages of heart failure. “I rarely tell my patients to avoid all salt,” she said. “Rather, just be mindful of salt intake, avoid fried foods, canned vegetables and pickle juice. You’d be surprised how many people admit to drinking pickle juice.”
