Protect against heart failure

By Amy Northrop

Your heart is clearly the most important muscle in your body. It’s made to beat powerfully and continuously minute after minute, day after day, without rest for your entire life. It should not weaken, but if it does – for any reason – the result is heart failure.

“The term sounds really horrible,” said Dr. Darcy Green Conaway,

About Dr Green Conaway

a cardiologist with Cardiovascular Specialists of Lawrence. “But it doesn’t mean that the heart stopped working. It’s simply not pumping as effectively as it should to get blood and oxygen to the cells of the body.”

Heart failure is the leading cause of hospitalization for Americans age 65 and over. Although age is not the primary reason for the weakening of the heart, there is some correlation. The most common risk factors are:

  • Coronary artery disease
  • High blood pressure
  • Sedentary lifestyle
  • Diabetes
  • Obesity
  • Smoking
  • Family history of heart disease/heart failure

Damage to the heart muscle can develop gradually as a result of an infection or disease of the heart. It can also occur as an after-effect of a heart attack.

When the left side of the heart fails to pump with enough force, fluid may collect in the lungs, making it more difficult to breathe and causing shortness of breath, particularly during exercise or while lying in bed. When backups occur on the right side, fluid begins to collect in the lower part of the body, leading to puffy legs and feet.

“The key to preventing heart failure is to start exercising early in life, and make it a lifelong habit,” said Dr. Green Conaway. “Exercise strengthens the heart, just as it does other muscles in the body. It also boosts circulation, strengthens the cardiovascular system, lowers blood pressure and cholesterol, and helps cells use oxygen more efficiently.”

One large study that followed men age 45 and over for nearly eight years found those who were the most physically active were least likely to develop heart failure. On the other hand, men who sat five or more hours a day and got little exercise had more than double the risk of more active men.

Cardiovascular Specialists of Lawrence offers a way to better manage your heart health with "Take Heart" – a heart risk assessment to identify your individual risk factors for heart disease. To schedule a heart risk assessment, call (785) 505-3636 or ask your primary care provider which heart risk assessment option is right for you.
