It depends what type of angina you have. With stable angina (the most common form there is a specific pattern. Angina is primarily classified as stable angina and unstable angina. Tabacum 3x has cured cases of angina pectoris in patients with arterio-sclerosis. Especially useful in anginas caused by tobacco also in the intermittent hearts of the aged. Stable angina refers to a variety of cardiology angina and manifested the characteristic pain, gradually increasing in certain loads and stops when removed. In the moments of physical and emotional stress coronary arteries can not provide the increased demand of the heart muscle of oxygen, which causes. Unstable angina is less common than stable angina, but it's more dangerous.

is coronary artery disease, obstruction of the coronary arteries due to atherosclerosis. The pattern of angina may remain stable for months or years. But as the disease advances, the anginal episodes may increase in frequency or duration, become less. Angina is usually caused by atherosclerosis (a narrowing of the arteries which supply blood to the heart).

Q: A: Angina, also known as angina pectoris, is a painful but temporary heart condition caused primarily by constriction of veins and arteries. Once these blood vessels become tight, the hearts oxygen supply is reduced and the result is pain in the chest, jaw, neck, throat or arms. The pain usually subsides once the blood flow is restored. In essence, angina is the cardiac equivalent of a headache. The most common cause of angina symptoms is a condition called arteriosclerosis, or a hardening of the arteries. As veins and arteries age, they lose much of their elasticity. When the heart rate increases, as it does during exercise, the oxygenated blood must tudo pass through very narrow blood vessels. The heart receives less of this blood, causing it to feel deprived.

In addition, the centers for Disease control and Prevention (CDC) reports that the risk of chd (Coronary heart disease stroke, and pvd (Peripheral vascular disease) is reduced within 12 years of smoking cessation. In another study, it was found that, after one year, the prevalence of angina in smoking men under 60 after an initial attack was 40 less in those having quit smoking compared to those that continued. Studies have found that there are short-term and long-term benefits to smoking cessation. Other medical problems edit Other cardiac problems edit myocardial ischemia can result from: a reduction of blood flow to the heart that can be caused by stenosis, spasm, or acute occlusion (by an embolus ) of the heart's arteries. Resistance of the blood vessels. This can be caused by narrowing of the blood vessels; a decrease in radius. 26 Blood flow is proportional to the radius of the artery to the fourth power. 27 reduced oxygen-carrying capacity of the blood, due to several factors such as a decrease in oxygen tension and hemoglobin concentration.

Myocardial ischemia comes about when the myocardium (the heart muscle) receives insufficient blood and oxygen to function normally either because of increased oxygen demand by the myocardium or because of decreased supply to the myocardium. This inadequate perfusion of blood and the resulting reduced delivery of oxygen and nutrients are directly correlated to blocked or narrowed blood vessels. Some experience "autonomic symptoms" (related to increased activity of the autonomic nervous system ) such as nausea, vomiting, and pallor. Major risk factors for angina include cigarette smoking, diabetes, high cholesterol, high blood pressure, sedentary lifestyle, and family history of premature heart disease. A variant form of angina— prinzmetal's angina —occurs in patients with normal coronary arteries or insignificant atherosclerosis. It is high believed caused by spasms of the artery. It occurs more in younger women.

15 coital angina, also known as angina d'amour, is angina subsequent to sexual intercourse. 16 It is generally rare, except in patients with severe coronary artery disease. 16 Major risk factors edit citation needed routine counselling of adults to advise them to improve their diet and increase their physical activity has not been found to significantly alter behaviour, and thus is not recommended. 18 Conditions that exacerbate or provoke angina 19 One study found that smokers with coronary artery disease had a significantly increased level of sympathetic nerve activity when compared to those without. This is in addition to increases in blood pressure, heart rate, and peripheral vascular resistance associated with nicotine, which may lead to recurrent angina attacks.

9 The primary cause of cardiac syndrome x is unknown, but factors apparently involved are endothelial dysfunction and reduced flow (perhaps due to spasm) in the tiny "resistance" blood vessels of the heart. 10 Since microvascular angina is not characterized by major arterial blockages, it is harder to recognize and diagnose. Microvascular angina was previously considered a rather benign condition, but more recent data has changed this attitude. Studies, including the women's Ischemia syndrome evaluation (wise suggest that microvascular angina is part of the pathophysiology of ischemic heart disease, perhaps explaining the higher rates of angina in women than in men, as well as their predilection towards ischemia and acute coronary syndromes. 14 Signs and symptoms edit Angina pectoris can be quite painful, but many patients with angina complain of chest discomfort rather than actual pain: the discomfort is usually described as a pressure, heaviness, tightness, squeezing, burning, or choking sensation. Apart from chest discomfort, anginal pains may also be experienced in the epigastrium (upper central abdomen back, neck area, jaw, or shoulders.

This is explained by the concept of referred pain, and is due to the fact that the spinal level that receives visceral sensation from the heart simultaneously receives cutaneous sensation from parts of the skin specified by that spinal nerve's dermatome, without an ability. Typical locations for referred pain are arms (often inner left arm shoulders, and neck into the jaw. Angina is typically precipitated by exertion or emotional stress. It is exacerbated by having a full stomach and by cold temperatures. Pain may be accompanied by breathlessness, sweating, and nausea in some cases. In this case, the pulse rate and the blood pressure increases. Chest pain lasting only a few seconds is normally not angina (such as precordial catch syndrome ).

The pathophysiology of unstable angina is the reduction of coronary incubatietijd flow due to transient platelet aggregation on apparently normal endothelium, coronary artery spasms, or coronary thrombosis. 6 7 The process starts with atherosclerosis, progresses through inflammation to yield an active unstable plaque, which vertigo undergoes thrombosis and results in acute myocardial ischemia, which, if not reversed, results in cell necrosis (infarction). 7 Studies show that 64 of all unstable anginas occur between 22:00 and 08:00 when patients are at rest. 7 8 In stable angina, the developing atheroma is protected with a fibrous cap. This cap may rupture in unstable angina, allowing blood clots to precipitate and further decrease the area of the coronary vessel's lumen. This explains why, in many cases, unstable angina develops independently of activity. 7 Cardiac syndrome x edit main article: Cardiac syndrome x cardiac syndrome x, sometimes known as microvascular angina is characterized by angina-like chest pain, in the context of normal epicardial coronary arteries (the largest vessels on the surface of the heart, prior to significant branching). The original definition of cardiac syndrome x also mandated that ischemic changes on exercise (despite normal coronary arteries) were displayed, as shown on cardiac stress tests.

4 Symptoms typically abate several minutes after activity and recur when activity resumes. In this way, stable angina huiduitslag may be thought of as being similar to intermittent claudication symptoms. Other recognized precipitants of stable angina include cold weather, heavy meals, and emotional stress. Unstable angina edit Unstable angina (UA) (also " crescendo angina this is a form of acute coronary syndrome ) is defined as angina pectoris that changes or worsens. 5 It has at least one of these three features: it occurs at rest (or with minimal exertion usually lasting more than 10 minutes it is severe and of new onset (i.e., within the prior 46 weeks) it occurs with a crescendo pattern (i.e., distinctly. Ua may occur unpredictably at rest, which may be a serious indicator of an impending heart attack. What differentiates stable angina from unstable angina (other than symptoms) is the pathophysiology of the atherosclerosis.


There is a weak relationship between severity of pain and degree of oxygen deprivation in the heart africa muscle (i.e., there can be severe pain with little or no risk of a myocardial infarction (heart attack) and a heart attack can occur without pain). In some cases, angina can be quite severe, and in the early 20th century this was a known sign of impending death. 2, however, given current medical therapies, the outlook has improved substantially. People with an average age of 62 years, who have moderate to severe degrees of angina ( grading by classes, ii, iii, and IV) have a 5-year survival rate of approximately. 3, worsening angina attacks, sudden-onset angina at rest, and angina lasting more than 15 minutes are symptoms of unstable angina (usually grouped with similar conditions as the acute coronary syndrome ). As these may precede a heart attack, they require urgent medical attention and are, in general, treated in similar fashion to myocardial infarction. Contents Classification edit Illustration depicting angina Stable angina edit Also known as 'effort angina this refers to the classic type of angina related to myocardial ischemia. A typical presentation of stable angina is that of chest discomfort and associated symptoms precipitated by some activity (running, walking, etc.) with minimal or non-existent symptoms at rest or after administration of sublingual nitroglycerin.

For other uses, see, angina symptome (disambiguation). Angina, also known as angina pectoris, is chest pain or pressure, usually due to not enough blood flow to the heart muscle. Angina is usually due to obstruction or spasm of the coronary arteries. 1, other causes include anemia, abnormal heart rhythms and heart failure. The main mechanism of coronary artery obstruction is an atherosclerosis. The term derives from the. Latin angere to strangle and pectus chest and can therefore be translated as "a strangling feeling in the chest".
