Know Your Family History
Control Your Blood Pressure

Watch your blood pressure because hypertension, or high blood pressure, is known to raise the risk for heart disease. Because there are no symptoms that are exclusive to high blood pressure, you’ll need to frequently check your blood pressure. And although there are no symptoms for hypertension, that’s just because it’s a precursor to many other terrible things, like heart disease or stroke.
Watch Your Cholesterol

Cholesterol is needed for your body to function, but too much of a good thing is always a bad thing. Make sure your HDL levels, aka your good cholesterol levels, are high and your LDL levels, aka the bad cholesterol, are low by limiting saturated fats and avoiding trans fats. When you have too much high cholesterol, it will clog your arteries, raising your risk for heart disease.
Watch Your Weight

Watching your weight is about more than just looking good at the beach or fitting into your favorite pair of jeans. It’s an extremely complicated relationship, but obesity has been known to double your risk of heart disease. Even reducing your weight by a few pounds will dramatically help your overall health, not just your risk of heart disease.
Eat Healthy

Limiting your intake of saturated fats, high-sodium foods, and added sugars will limit a lot of the junk modern diets put our bodies through. Replacing these foods with healthy foods will take it a step further and give our bodies what it needs. For heart disease prevention, go out of your way for heart-healthy foods like red vegetables, salmon, nuts, berries, and beans.
Exercise Regularly

Exercise seems to be on every conceivable health list, and there’s a reason for that: it works. It’s obviously a great way to lose weight and improve your daily routine, but it also strengthens your heart and improves circulation, two things that will fight heart disease. Exercising for 30 minutes two to three days a week prevents mid-sized arteries from aging, and bumping that up to four to five days can help even your larger arteries.
Limit Alcohol

At the end of a long day, it’s nice to pour yourself a glass of your choice poison, sit back, and relax with loved ones. It’s not, however, healthy to indulge too much. Men shouldn't have more than two glasses of alcohol a day, and women shouldn't have more than one. Drinking more than three will temporarily raise your blood pressure, while consistently drinking more than one or two will raise it over time.
Don’t Smoke

At this point, the world is well aware that smoking is very, very dangerous to your health. Not only is smoking linked to 16 different types of cancer, but it’s been known to cause heart disease as well. This even includes second-hand smoke, which is even more cancerous than mainstream smoking. Overall, smoking will damage the lining of your arteries, allowing fats to build up, clogging the arteries. This, of course, leads to heart disease.
Avoid e-Cigarettes
Manage Stress

80% of Americans claim to experience stress on a frequent basis, but how often do people go about trying to keep their stress down? Not very much, which is a problem because stress does lead to heart problems. In fact, like most other things that can be done to prevent heart disease, learning to manage your stress will help your overall health levels. Not doing so can lead to higher blood pressure and heart attacks, in addition to heart disease.
Manage Diabetes

A number of dietary changes can be put in place to help prevent diabetes, but if you have already been diagnosed, managing your diabetes goes a long way. If not, diabetes will damage your blood vessels and nerves. In fact, most people with diabetes die of heart disease, so taking care of your diabetes is especially important because people with diabetes are at an even higher risk of heart disease.
Get Enough Sleep

For some reason, most people don’t seem to think of sleep when they think of healthy lifestyle changes. Without sleep, though, your body will fall into disrepair. As it relates to heart disease, getting enough high-quality sleep will give your heart time to rest and will provide your heart with the specific proteins it needs.
Sit Less

Our culture is very sedentary now, but humans were made to move around. Most of us sit at work for eight hours a day, commute another hour (or two), and then watch five hours of TV. That's 14 hours of sitting, which is especially dangerous because excessive sitting has been linked to numerous health issues, even for people who exercise. Make sure you take breaks from sitting, going on walks and standing while you work. Walk or bike to places nearby.
Drink Red Wine

Nobody is 100% sure why there is a connection between drinking red wine and a healthy heart, but nobody is complaining. It’s an excuse to drink wine! (In moderation, of course). It's supposed to provide your body with crucial antioxidants, reduce the “bad cholesterol,” and prevent blood clots. Plus, it makes dinner more fun! What’s not to love?
Regular Doctor Check-Ups

It should go without saying, but make sure you have regular check-ups. They are the only ones who can't catch, diagnose, and treat your problems with accuracy. The older you are or the higher your family history of heart disease is, the more important regular doctor’s visits are because your risk factors are higher. And when you go, make sure to ask them what you personally can do better about preventing and managing heart disease in your life.
Stay Informed

Science is always changing. Because of this, doctors are always finding new causes for diseases and treatments for diseases. This is especially true for heart disease, considering its prevalence in Western societies. Watch for new developments so that you always know the best way to take care of yourself and your loved ones.
Increase Healthy Fat Intake
Watch Your Triglyceride Levels

Triglycerides are another type of fatty acid in the body. When they’re high, you’re putting your health in danger. High triglycerides could raise your risk of heart disease, especially if you already have high cholesterol. The best way to lower triglyceride levels is by following a heart-healthy diet and exercising regularly.
Reduce Your Sugar Intake

Even if a sugar is natural, it’s still bad for you. Things like agave and honey are still processed like sugar and can still pack on pounds. Limiting sugars may be difficult, but doing so unveils a host of health benefits from lower weight to a healthier heart and less inflammation. Sugars like stevia and erythritol are low on the glycemic index, so a much better choice for your body and sweet tooth.

Take Your Medication
Eat More Fish
Treat Mental Problems

Good mental health is paramount to a healthy heart. The American Heart Association found that there’s a strong link between depression and heart disease. Not only can it increase the risk of heart disease, but it could also appear following a heart attack. Keeping anxiety and depression in check is the first step to a healthy body.
