Blood lipids include a type of fat called triglycerides and a waxy substance called cholesterol. Cholesterol has two components, low-density lipoprotein (LDL) and high-density lipoprotein (HDH). High levels of LDL cholesterol and triglycerides, and low levels of HDL cholesterol are linked to heart disease.

High levels of LDL cholesterol, often called the “bad” cholesterol, are associated with heart disease. LDL cholesterol can stick to artery walls causing the formation of blockages or plaques. As the plaques build up (a condition called atherosclerosis) they reduce or block the flow of blood to the heart, which can result in chest pain and lead to a heart attack.

Low levels of HDL cholesterol, the “good” or “healthy” cholesterol, can also increase your risk of heart disease. HDL cholesterol is involved in removing the “bad” LDL cholesterol from your body. If your levels of HDL cholesterol are not high enough, then less of the “bad” cholesterol is removed.

High levels of triglycerides are also associated with heart disease because they can also cause a buildup of plaques. Triglycerides are stored in fat cells in your body and supply your body with energy between meals.

A lipid profile is a blood test that can tell you if you have high levels of lipids (hyperlipidaemia) in your blood.

What types of drugs are used for treating heart disease?

The most common medicines used to treat and help prevent worsening heart disease include:

  • Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs)
  • Calcium channel blockers / calcium antagonists
  • Beta blockers
  • Isosorbide or nitroglycerin
  • Antiplatelet drugs, like aspirin or clopidogrel
  • Warfarin or other blood thinners

Why is physical activity so important in preventing heart disease?

Physical activity prevents heart disease by helping you maintain a healthy weight and keeping your joints mobile to allow you to do daily activities such as climbing stairs and shopping. This keeps your heart pumping and blood and oxygen flowing around your body. Physical activity has also been shown to lower stress hormones and reduce your risk of depression or cognitive decline (this is how you think or learn, and your judgment skills). When you feel good about yourself and the world you live in, then you are more inclined to be active and to take good care of yourself, which helps your heart as well. It also boosts your immune system, causing changes in antibodies and white blood cells which are the body’s immune cells that fight disease. This can lower your risk of catching infections, such as the cold or the flu, or help flush bacteria out of the lungs and airways. Continue reading

How can you check for heart disease at home?

You can check for heart disease at home by measuring your pulse rate and your blood pressure if you have a blood pressure monitor. To measure your pulse you will need an analog watch (one with a clock face rather than digital numbers) with a second hand. Place your index and middle finger of your hand on the hollow part of your inner wrist of the other arm, just below the base of the thumb. You should feel a tapping or pulse against your fingers, that is your heartbeat. Look at your watch and count the number of taps you feel in 10 seconds. Multiply that number by 6 to find out your heart rate for 1 minute. Continue reading
