How healthy is your heart?

Cardiovascular disease (CVD) is the leading cause of death in the United States, according to the latest statistics from the American Heart Association (AHA). To put this in perspective, on average, someone in the U.S. dies of CVD every 34 seconds. Every 3 minutes and 17 seconds someone dies of a stroke.

There are several factors – including family history, age, gender, race, cholesterol, blood pressure, smoking history and diabetes – that contribute to the risk of developing CVD. Let’s look at just one: cholesterol.

The highs and lows of cholesterol

When it comes to cholesterol, numbers matter. Cholesterol travels through your blood on proteins called “lipoproteins.” Two types of lipoproteins carry cholesterol throughout the body:

Basically, you want your LDL number to be as low as possible and your HDL to be as high as possible.

The average LDL (low-density lipoprotein, often called the bad cholesterol) in the U.S. is close to 130. Average should not be confused with what’s normal. When you’re born, your LDL is 30! So, how low should you go? Experts say, “the lower, the better.” Experts now recommend an LDL cholesterol level under 50 for high-risk individuals, much below the previous 70. There are many good pharmaceutical therapies available to lower LDL.

When it comes to HDL, 60 or higher is optimal. There are no drugs that can raise your HDL, but there’s plenty you can do on your own to increase it, including stopping smoking, maintaining a healthy weight, eliminating trans fats from your diet and exercising.

Walking is a simple and abundantly available exercise here on the Island, and it’s so good for you. In fact, peer-reviewed studies published in the Journal of the American Medical Association, older adults who walk three to four miles per day—6,000 to 9,000 steps—are 40 to 50 percent less likely to suffer a heart attack or stroke than those who walk a mile (2,000 steps) per day.

Good heart health promotes better brain health

If you need more reasons to improve your heart health, the AHA just last week released results of a study that found that improving heart health in midlife and beyond was associated with a lower prevalence of stroke and dementia risk factors around two decades later.

While the findings are considered preliminary until full results are published in a peer-reviewed journal, what has been discovered is promising. For example, from midlife to late life, those in the study who maintained ideal cardiovascular health had 33 percent lower odds of brain microbleeds and 37 percent lower odds of having infarcts compared to people whose scores declined.

Regular checkups and screenings can identify risk early

February is Heart month, the time to celebrate the ones you love and the heart that loves them. With this in mind, I urge you to get regular checkups and talk to your doctor about any family history of high cholesterol, diabetes and heart issues that could put you at high risk for coronary disease.
