Question

About cardiac muscles and precaution of heart

Answer 1

The heart is a muscle that pumps blood to all parts of the body. When the heart chambers contract, blood is pumped out of the heart through the aorta (the main artery from the heart) carrying oxygen and nutrients to the rest of the body.

Answer 2

Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control.

It does this through specialized cells called pacemaker cells. These control the contractions of your heart. Your nervous system sends signals to pacemaker cells that prompt them to either speed up or slow down your heart rate.

Your pacemaker cells are connected to other cardiac muscle cells, allowing them to pass along signals. This results in a wave of contractions of your cardiac muscle, which creates your heartbeat. 

You want what’s best for your heart. And it’s simpler than you might think. These  lifestyle changes can help prevent a heart attack and heart disease.

Eat to be your best. Add plenty of fruits and veggies, grains, and foods high in omega-3 fatty acids like fresh tuna or herring to your diet. Cut down on salt, saturated fats, sweets, and red meats. Avoid trans fats and food with “hydrogenated” or “partially hydrogenated” ingredients. Variety in your diet is a good way to get all the nutrients you need.

Take it easy. Find a relaxation method that works for you. Yoga, meditation, dedicated time to unwind after work -- these can help keep your stress levels down. Stressful emotions such as anger and hostility may also lead to heart attack risk, so keep calm and be cool. 

Ban smoking. If you never started smoking, that’s perfect! If you already quit, excellent. If you still smoke, stop. Talk to your doctor to find out what method will work best for you.  Even people who smoke fewer than five cigarettes a day can have early signs of heart disease. Start now. In just 1 year you can reduce your risk of a heart attack.

What You Can Do to Prevent a Heart Attack

Keep tabs on your blood pressure. If it’s too high, your risk of a heart attack and heart disease goes up. Stress management, a healthy diet, and regular exercise can help you manage your blood pressure. Your doctor may also prescribe medications to lower your levels. 

Mind your blood sugar. Too much sugar in your blood can damage your arteries. This happens with prediabetes as well as diabetes. Work with your doctor to control your blood sugar levels.  That may lower your chance of having a heart attack or stroke. Remember, you can’t tell if you have diabetes (or high blood pressure, or high cholesterol) based on how you feel.

Be smart about cholesterol. When blood flows through your blood vessels, it can drop traces of cholesterol, fat, and calcium, creating a buildup of plaque in your arteries. Too much of that plaque makes a heart attack more likely. If you don’t know your cholesterol levels, ask your doctor for a blood test.

Keep in mind, there are two kinds of cholesterol. One called LDL is bad for your heart. The other, HDL, can help protect you from heart disease. You can improve your levels with exercise and a diet low in unhealthy fats. Some people may also need to take medicine that lowers cholesterol.

Check your weight. If you have extra pounds, it can put your heart at risk. Exercise and a good diet help. Ask your doctor or a dietitian what your weight should be and how to get there. 

Ask about aspirin. Talk with your doctor about taking an aspirin every day. In some people, this reduces the risk of heart attack.
