Coronary Artery Disease

Coronary heart disease CHD , or coronary artery disease, develops when the coronary arteries become too narrow. The coronary arteries are the blood vessels that supply oxygen and blood to the heart. CHD tends to develop when cholesterol builds up on the artery walls, creating plaques.

These plaques cause the arteries to narrow, reducing blood flow to the heart. A clot can sometimes obstruct the blood flow, causing serious health problems. Coronary arteries form the network of blood vessels on the surface of the heart that feed it oxygen.

If these arteries narrow, the heart may not receive enough oxygen rich blood, especially during physical activity.

CHD can sometimes lead to heart attack. CHD develops as a result of injury or damage to the inner layer of a coronary artery. This damage causes fatty deposits of plaque to build up at the injury site. These deposits consist of cholesterol and other waste products from cells. This buildup is called atherosclerosis. If pieces of plaque break off or rupture, platelets will cluster in the area in an attempt to repair the blood vessel.

This cluster can block the artery and reduce or block blood flow, which may lead to a heart attack. CHD can lead to angina. This is a type of chest pain linked to heart disease.

CHD can also lead to shortness of breath. If the heart and other organs do not receive enough oxygen, any form of exertion can become very tiring, which may cause a person to pant for air.

Heart attack occurs when the heart muscle does not have enough blood or oxygen, such as when a blood clot develops from plaque in one of the coronary arteries. The formation of a blood clot is called coronary thrombosis. This clot, if it is big enough, can stop the supply of blood to the heart. The first symptom is usually chest pain that spreads to the neck, jaw, ears, arms, and wrists, and possibly to the shoulder blades, back, or abdomen.

Changing position, resting, or lying down is unlikely to bring relief. The pain is often constant but may come and go. It can last from a few minutes to several hours. A heart attack is a medical emergency that can result in death or permanent heart damage. If a person is showing symptoms of a heart attack, it is vital to call the emergency services immediately.

Treatment tends to involve making healthful lifestyle changes, such as quitting smoking , adopting a healthful diet, and getting regular exercise. In the past, some people used aspirin to lower their risk of CHD, but current guidelines only recommend this for people with a high risk of heart attack, stroke , angina, or other cardiovascular events.

Doctors now recommend focusing on lifestyle strategies, such as adopting a healthful diet and getting regular moderate to intense exercise. These strategies can reduce the risk of atherosclerosis. The following surgical procedures can open or replace blocked arteries if they have become very narrow, or if symptoms are not responding to medications:. On rare occasions, a person may need a heart transplant.

However, this is only if the heart has severe damage and treatment is not working. Here, learn more about treating heart attack. To better control blood cholesterol levels:. Having high levels of lipoprotein a specifically is also linked to a higher risk of cardiovascular disease and CHD.

A doctor can perform a physical examination, take a thorough medical history, and order a number of tests to diagnose CHD. For example:. CHD develops when coronary arteries become too narrow.

The condition causes blockages in the arteries that feed oxygen-rich blood to the heart. CHD can be difficult to treat and may lead to a heart attack or stroke. However, people can take steps to reduce their risk of CHD by getting regular exercise, adopting a healthful diet, and avoiding or quitting tobacco.

People should seek immediate medical attention if they have chest pain and breathlessness, as this could indicate a heart attack. CHD is the most dangerous cardiovascular disease, as it causes the most deaths of any heart disease in the United States. Having undetected or untreated high blood pressure or high cholesterol can lead to a heart attack without causing any prior symptoms. Be sure to see a doctor regularly and seek regular blood tests.

Coronary Artery Disease - Coronary Heart Disease

Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart called coronary arteries. Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis. It is sometimes called coronary heart disease or ischemic heart disease. For some people, the first sign of CAD is a heart attack.

Shortness of breath. If your.

Warning Signs of a Heart Attack

Coronary artery disease means narrowing of the coronary arteries arteries that supply blood to the heart. This narrowing is due to a buildup in the walls of the arteries of plaque deposits made up of cholesterol, other fats, and calcium —a process called atherosclerosis hardening of the arteries. If a plaque becomes delicate and breaks, a blood clot will quickly form that can block blood flow in the artery and may lead to a myocardial infarction death of the heart muscle area supplied by the blocked artery , often referred to as a heart attack. Coronary artery disease can develop slowly without any symptoms. Angina —chest pain that can radiate to or sometimes is limited to the shoulders, arms, or jaw.

Coronary artery disease CAD , also called coronary heart disease CHD , ischemic heart disease IHD , [13] or simply heart disease , involves the reduction of blood flow to the heart muscle due to build-up of plaque atherosclerosis in the arteries of the heart. Usually symptoms occur with exercise or emotional stress , last less than a few minutes, and improve with rest. Risk factors include high blood pressure , smoking , diabetes , lack of exercise, obesity , high blood cholesterol , poor diet, depression , and excessive alcohol. Ways to reduce CAD risk include eating a healthy diet , regularly exercising, maintaining a healthy weight, and not smoking. In , CAD affected million people and resulted in 8.

Coronary Artery Disease (CAD)

Coronary artery disease develops when the major blood vessels that supply your heart become damaged or diseased.

Все это было так неестественно, так непохоже на Хейла, а список преступлений больше напоминал перечень сданного в прачечную белья. Он признался во всем - в том, как понял, что Северная Дакота всего лишь призрак, в том, что нанял людей, чтобы те убили Энсея Танкадо и забрали у него кольцо, в том, что столкнул вниз Фила Чатрукьяна, потому что рассчитывал продать ключ от Цифровой крепости. Сьюзан дошла до последней строки. В ней говорилось о том, к чему она совершенно не была готова. Последние слова записки стали для нее сильнейшим ударом.

Она была спрятана под землей на глубине 214 футов для защиты от взрывов и воздействия магнитных полей. Вся деятельность в комнате управления относилась к категории Совершенно секретно. УМБРА, что было высшим уровнем секретности в стране.

Даже если АНБ расскажет о ТРАНСТЕКСТЕ, Танкадо им уже ничем не поможет. Стратмор молчал. Положение оказалось куда серьезнее, чем предполагала Сьюзан.

Внезапно она встала. В голосе ее прозвучала удивительная решимость: - Мы должны установить с ним контакт. Должен быть способ убедить его не выпускать ключ из рук. Мы обязаны утроить самое высокое сделанное ему предложение. Мы можем восстановить его репутацию.

Рука консьержа только что покинула ячейку под номером 301. Беккер поблагодарил его и быстро зашагал, ища глазами лифт. Туда и обратно, - повторил он мысленно. ГЛАВА 31 Сьюзан вернулась в Третий узел. После разговора со Стратмором она начала беспокоиться о безопасности Дэвида, а ее воображение рисовало страшные картины.

Одно движение, и он выстрелит. Но стрелять не понадобилось. Халохот был мертв. Беккер отшвырнул пистолет и без сил опустился на ступеньку.
