The addition of calcium channel blockers to background nitrate therapy has been shown to reduce cardiac events in patients with variant angina 9.

American Journal of Cardiovascular Drugs: Exercise ECG stress testing is typically negative but during the hot phase, exercise-induced spasm may occur in half of the variant angina patients 4. They are also tested by ECG which may suggest variant angina if it shows elevations in the ST segment or an elevated ST segment plus a xe of the R wave during symptoms that are triggered by a provocative agent e.

Induction of coronary artery spasm by acetylcholine in patients with variant angina: Two approaches have evolved in the diagnosis of variant angina. Provocation of coronary artery spasm by the cold pressor test: The pain or discomfort: In contrast to patients with angina pectoris secondary to coronary artery atherosclerosis, people with variant angina are generally younger and have fewer risk factors for coronary artery disease except for smokingwhich is a common and very significant prinzmeatl factor for both types of angina.

Started inthis collection now contains interlinked topic pages divided into a tree of 31 specialty books and chapters. Long-acting nitroglycerins such as isosorbide dinitrate or intermittent use of short-acting vxriante to treat acute symptoms may be added to the calcium channel blocker regimen in individuals responding sub-optimally to the channel blockers.

Guidelines for diagnosis and treatment of patients with vasospastic angina coronary spastic angina JCS Long-term prognosis of “variant” angina with medical treatment. A variant form of angina pectoris caused by coronary artery amgina, usually occurring spontaneously and frequently associated with ST segment elevation.

Individuals with certain severe complications of variant angina require immediate therapy. Despite the availability of effective therapies for coronary artery spasm, the diagnosis of variant angina is infrequently considered in patients with angina. Short-acting nitrates are utilised for acute episodes whereas the long-acting nitrates are used to prevent vasospastic episodes.

Coronary microvascular disorders may cause rest angina in patients with normal angiography, which may be distinguished from variant angina by excluding coronary artery spasm with provocative spasm testing. Unlike cases of atherosclerosis-related stable anginathese symptoms are often unrelated to exertion and occur in night or early morning hours. The only evidence of the presence of totally asymptomatic variant angina would be detection of diagnostic changes on fortuitously conducted ECGs.

Variant angina

The pain from variant angina is caused by a spasm in the coronary arteries which supply blood to the heart prinzzmetal. Although the classical apical ballooning may distinguish it from variant angina, some investigators speculate that this curious entity is due to multivessel spasm. These attacks can be very painful. Endocarditis infective endocarditis Subacute bacterial endocarditis non-infective endocarditis Libman—Sacks endocarditis Nonbacterial thrombotic endocarditis.

For a portion of patients, variant angina may be a manifestation of a more generalized episodic smooth muscle -contractile disorder such as migraineRaynaud’s phenomenonor aspirin-induced asthma. Variant angina of Prinzmetal with normal coronary arteriograms.
