Heart disease cases are rising rapidly these days, and one of the most common and serious conditions is heart blockage. It occurs when the blood vessels that deliver blood to the heart are blocked or narrowed. Early detection of this condition is particularly critical because it poses a higher risk of heart attack, heart failure and death in case the condition remains undetected. Here's a simple explanation of how and why heart blockage occurs.
The heart requires an uninterrupted supply of oxygen and nutrients to be able to maintain proper operation. The coronary arteries carry this supply. These arteries may over time accumulate fat, cholesterol, calcium or inflammatory cells on the inner walls. This accumulation is in a layer known as plaque. They augment and restrict the blood flow to the heart and make the arteries narrower as the plaque expands. This is acoustically called heart blockage.
Heart blockage is not an acute occurrence. It progresses gradually and might have no initial signs. The risk can be augmented by several factors:
1. High cholesterol
The abundance of bad cholesterol may result in the deposition of plaque along the blood vessels. This leads to a higher risk of blockage with time.
2. High blood pressure
The damage to arterial walls by high blood pressure increases the ease with which fats and cholesterol stick causing a blockage.
3. Diabetes
High blood pressure may damage blood vessels, and thus block them, putting people with diabetes at a higher risk.
4. Unhealthy lifestyle
The risk may be aggravated by such habits as smoking, taking tobacco, eating junk food, and being overweight. The process of smoking, specifically, makes the blood inflamed and thicker, which can result in the formation of a clot.
5. Stress
It is also possible that long-term stress increases the risk of heart disease and causes heart blockage.
Heart blockage may not exhibit any early symptoms but some of its common symptoms include:
