How many push-ups can you do? It may sound like an arbitrary question, but it turns out the number of push-ups you can do may be tied to your future risk of a heart attack, according to a study published in JAMA Network Open. 

The study, which followed young firefighters for 10 years, found that those able to perform more than 40 push-ups at the outset of the study had a much lower risk for a heart-related problem than firefighters who did fewer than 10 push-ups. 

When it comes to your heart health, you probably know some of the most important numbers to watch for: blood pressure, weight, cholesterol – especially low-density lipoprotein (LDL), the “bad” cholesterol. Did you know you should also keep tabs on your triglycerides to help prevent your risk of heart disease?

Triglycerides are a type of lipid, or fat, in your blood. In healthy amounts, they give you energy. However, high triglyceride levels may increase your risk of heart disease. Here’s what you need to know about them. 

Over the last decade, experts have told us getting seven to eight hours of sleep every night can help protect us against heart disease. Ever wondered why? Researchers think they might have the answer. Healthy, sound sleep triggers a mechanism designed to protect your arteries, according to a study published in Nature. 

Stress -- you can’t escape it. And it can wreak havoc on blood pressure. Exercise, meditation and hobbies are common, effective stress busters. So is having a social support system of friends and relatives. But if they’re not available, having your significant other present – even if it’s only in your mind – can help keep blood pressure controlled, according to a small study published in Psychophysiology. 

You’re probably aware of the toll everyday stress takes on your health. Headaches, weight gain, insomnia – the list goes on and on. But you may not realize how stress affects your oral health. People with greater levels of perceived stress report poorer oral health, according to a study published in BMC Oral Health. And poor oral health raises the risk for cardiovascular disease and diabetes.

It has become clear to me, after more than 35 years of medical practice, that the traditional approach to cardiovascular disease is missing the boat. Just look at these dismal statistics:

Alan Reisinger, MD, Baltimore, MD:
There are some unfortunately well entrenched myths about heart disease.

Almost half of all Americans make New Year’s resolutions, yet only a small percent actually achieves them. In fact, about 80 percent of resolutions fall by the wayside by February. 

Why do so many people give up? Some experts chalk it up to a lack of motivation. Remedies include setting up a weekly mini-goals and giving yourself rewards  each time you reach a goal. You can also strengthen your willpower.

Exercising, eating a healthy diet, getting enough sleep, managing weight, controlling stress and avoiding tobacco can help prevent heart attacks and strokes. But sometimes genetics trump even the healthiest of lifestyles. You can do everything right and still be diagnosed with coronary artery disease a condition that significantly raises your risk for it, including high blood pressure, high cholesterol or type 2 diabetes.

If you have type 2 diabetes, you’re probably aware of how difficult it can be to manage. You may struggle keeping your A1c levels in line despite exercising, managing your weight, eating a healthy diet and taking a prescription medication.
