What Exactly Happens During A Heart Attack?

Before going to explain the situation of heart attack we should get to know the process of heart work that how our heart works? Blood flows through your core and lungs in four moves: Oxygen-poor blood is received from the body by the right atrium and pumped through the tricuspid valve into the right ventricle.  The left atrium gets from the lung’s oxygen-rich blood and pumps it through the mitral valve to the left ventricle. And how does the heartbeat? Working together, the atria and ventricles contract and relax alternatively to make the heartbeat and pump blood. Your heart’s electrical system is the energy source that enables this. Your heartbeat is caused by electrical impulses traveling through your core along a unique pathway.

This shows the complete gateway that how blood in and out from the human heart. Now we will see what exactly happens during a heart attack? A network of blood vessels known as coronary arteries surround the muscle of the core and provide it with oxygen and nutrient-rich blood.  When a coronary artery is suddenly blocked, a heart attack happens, stopping blood flow to the heart muscle and damaging it. This is because a buildup of fat, cholesterol and other substances that are called plaque together can narrow the coronary arteries that supply the heart muscle with blood flow. This slow process is referred to as atherosclerosis.

Now, what are coronary arteries? And what is coronary artery disease? And we will also discuss the cause of coronary artery disease. Coronary artery disease which is also known as atherosclerosis causes most heart attacks. This is when the coronary arteries from a gradual build-up of fatty streaks that are plaque. These are the arteries that provide the heart muscle with oxygenated blood. The construction of fatty streaks narrows and stiffens the coronary arteries over time.

As the coronary arteries narrow, reaching the heart muscle becomes harder for oxygenated blood, sometimes causing angina-known pain and discomfort. If a piece of plaque breaks, a blood clot may form and block a coronary artery, cutting off a portion of the heart muscle from the blood supply. This triggers an assault on the core.

now what are the cause of coronary artery disease which prevents to heart to beat normal? Your coronary arteries generally have good soft walls when you’re young. As you get older, risk factors such as cigarette smoke toxins, elevated blood pressure mechanical injury, high cholesterol or blood sugar from a diet elevated in saturated fats and sugars, and absence of practice undermines the internal lining of your coronary arteries. These wounds begin a chain of occurrences in your coronary arteries that lead to the build-up of fatty streaks. There are a number of variables your risk of coronary artery disease is known to boost. Age, ethnicity, gender, personal or family history of heart attack or stroke are some risk factors you can’t do anything about.

Remedies for heart failure treatment may include medicines provided to treat a heart attack. Aspirin decreases blood clotting, thus assisting a narrowed artery to preserve blood flow.
