Coronary artery disease (CAD) can be treated effectively, but it has no cure. You can help prevent your CAD from progressing by carefully following your doctor’s advice and making some lifestyle changes.

Kick Your Smoking Habit

Chemicals in cigarettes may make it easier for plaque to build up on your artery walls. If you smoke, quitting is the single most important thing you can do to lower your risk of your CAD from progressing. Smoking also increases your heart rate and blood pressure, raising your risk of heart attack and stroke.1 If you’re ready to quit, ask your doctor for advice - he or she can recommend smoking cessation aids to help you kick the habit.

Maintain a Healthy Weight

Maintaining a healthy weight can help reduce the risk of CAD progressing. You can calculate your body mass index (BMI) to find out if you're at a healthy weight for you.

Calculate Your BMI

You can also measure your waist circumference to help determine if you’re at a healthy weight. You may be overweight if you're a woman whose waistline is more than 35 inches or a man whose waistline is more than 40 inches.

How to Measure Your Waist

  • Stand and wrap a tape measure around your stomach, midway between your hip bones and the bottom of your ribs.
  • Keep the tape snug around your waist, without compressing your skin.
  • Take the measurement after breathing out normally.

While your BMI and waist circumference can be helpful tools to determine if you may be overweight, only a trained healthcare professional can assess your individual health status and risks. So be sure to ask your doctor what a healthy weight is for you.


Eat a Heart-Healthy Diet

Even small changes to your diet can make a big difference in your heart health. You can start with these simple steps, but be sure to talk to your doctor before making any changes to your diet so you can develop a plan that’s best for you.

  • Eat more foods that contain whole grains.
  • Add a variety of fruits and vegetables.
  • Cut down on sugar and salt (sodium).
  • Limit your consumption of high-fat foods, such as red meat, cheese, and baked goods.
  • Reduce your consumption of bad fats, which can increase the amount of harmful LDL (bad) cholesterol in your bloodstream and reduce the amount of beneficial HDL cholesterol. Bad fats include saturated and trans fats, and are more likely to be solid at room temperature, such as butter and solid shortening.
  • Substitute bad fats with good ones that don’t raise your LDL cholesterol levels and have health benefits when eaten in moderation. Good fats include monounsaturated and polyunsaturated fats, which are more likely to be liquid at room temperature, such as sunflower, soybean, corn and olive oils.

Be More Active

A sedentary lifestyle increases your risk of coronary artery disease. So even if you can’t fit in regular workouts, try making activity a part of your daily life. By starting small, you’ll gradually build up your activity level, which may help whittle your waistline, control your blood pressure and cholesterol levels, and enhance your overall heart health.

Tips for Adding More Activity to Your Day

  • Take frequent breaks throughout the day to stretch and walk.
  • Do your regular household chores at a brisker pace.
  • Park farther away from the door when running errands or get off the bus at an earlier stop to add more steps to your day.
  • Take the stairs instead of the escalator or elevator.
  • Plan more active entertainment. For example, go bowling or bike riding instead of seeing a movie.
  • Go for a brisk walk with friends or family after dinner.

Be sure to talk to your doctor before you start or resume any kind of exercise program.


Reduce Stress

Experiencing stress from time to time is a normal part of life. However, unmanaged stress can affect your overall health and have a negative impact on your heart by:2

  • Increasing your heart rate
  • Raising your blood pressure
  • Causing irregular heart rhythms
  • Raising your cholesterol levels
  • Damaging your arteries
  • Causing the development and progression of coronary artery disease (atherosclerosis)
  • Weakening your immune system

In addition, many people turn to unhealthy habits to cope with stress, such as smoking, overeating and drinking too much alcohol - all of which have a negative impact on heart health.

Simple Ways to Reduce Stress

  • Laugh a Little. Research shows that laughter may help reduce stress, lower blood pressure, increase muscle relaxation and boost the immune system.3 So make it a point to add laughter to your day - whether that means watching silly animal videos on the internet or meeting a funny friend for lunch.
  • Take Time to Relax. From meditation to deep breathing exercises, there are a number of techniques to help relax your mind during times of stress. Find the technique that works best for you and stick with it.
  • Keep a Stress Diary. Taking note of the things that cause you stress can help you identify stressors - and find ways to avoid them in the future.
