Cardiovascular disease

Cardiovascular disease describes a group of illnesses that affect the blood vessels (veins and arteries) and heart. The word technically pertains to any illness that may have an effect on the cardiovascular system (used in MeSH), and also to those linked to atherosclerosis (an arterial disease). These conditions possess comparable mechanisms, treatments and causes. Cardiovascular illnesses are treated by interventional cardiologists, vascular surgeons, thoracic surgeons, neurologists and cardiologists, depending on which organ system is to be treated. There is a significant overlap in the field of expertise, and it is normal for specific procedures to be done by different kinds of medical specialists within a single hospital.

Many countries are being faced with the continuous rise in the rate of cardiovascular disease. In fact, heart disease takes the lives of more Americans than does cancer. Based on a large histological study (PDAY), vascular damage increases from the teenage years; thus, some preventive measures are recommended even at a younger age.

Once a heart problem has been diagnosed, atherosclerosis, which is the basic cause, has likely been progressing for years. It is therefore necessary to prevent it by altering risk issues such as eating healthy, exercising, and quitting smoking. Below are descriptions of several types of heart illnesses.

Aneurysm
An aneurysm refers to a restricted, blood-filled expansion of blood vessels, which is caused by an illness or deterioration of the wall of the vessel. It usually occurs in the arteries located at the bottom part of the brain (called the circle of Willis), and in the aorta (chief artery that comes out from the heart). As an aneurysm’s size increases, there is an added risk that it may rupture, resulting in serious hemorrhage or other problems that can even lead to fatality.

Angina
Angina is characterized by an extreme pain in the chest because of ischemia (insufficient blood due to inadequate supply of oxygen) of heart muscles, causing the spasm or blockage of coronary arteries (blood vessels of the heart). Coronary heart disease is the primary consequence of angina resulting from the cardiac arteries’ atherosclerosis. The word is derived from the Greek work “ankhon,” which means strangling, and the Latin word “pectus,” which means chest – thus, the direct translation would be “strangling feeling in the chest.”

It is uncommon to equate the gravity of angina with the risk of deadly cardiac circumstances. The connection between the intensity of the pain and the level of deprivation of oxygen may vary, as intense pain could be felt with little or no risk of heart attack, while heart attack can take place with virtually no pain.

A worsening attack of angina, swift onset angina while at rest, or angina that lasts for over fifteen minutes are indications of unbalanced angina, which is typically classified as acute coronary syndrome. This may be a warning of an impending heart attack or myocardial infarction, so a quick medical intervention is needed. This condition is also treated as an actual heart attack.

Atherosclerosis
Atherosclerosis is an illness which affects the arterial blood vessels, and a long-term swelling reaction in the arteries’ walls due of the build up of macrophage white blood cells. Atherosclerosis grows from LDL, or low-density lipoprotein molecules, that are being oxidized by free radicals (LDL-OX). Atherosclerosis normally starts in the early puberty stage, and is typically located in nearly all the main arteries.

  1. There are certain factors which influence our cardiovascular health. Some of these factors include: the type of diet, physical activity, stress levels and body fat. All of these factors can surely affect our overall well being.

    Thank you to this sharing and it is very good article.
