Variant Angina Pectoris

Abstract To study whether magnesium (Mg) deficiency is present in patients with variant angina, 24-hour Mg retention of low dose Mg (0.2 mEq/kg lean body weight) administered intravenously over 4 hours in 20 patients with variant angina was examined. [ncbi.nlm.nih.gov]

  • Coronary Atherosclerosis

    Such response could not be predicted by demographic factors, ECG changes, or degree of coronary atherosclerosis. [ncbi.nlm.nih.gov]

    Coronary atherosclerosis is initiated by endothelial dysfunction due to inflammation and increased low density lipoprotein-cholesterol (LDL-C) levels, followed by the deposition of lipids and macrophages from the lumen into the inner layer of the coronary [e-kcj.org]

  • Oral Ulcers

    After treatment with immunosuppressant, neither angina nor oral ulcer relapsed. We strongly believe that the variant angina is due to coronary vasospasm induced by Behçet's syndrome in this patient. [ncbi.nlm.nih.gov]

  • Chest Pain

    Another 23 subjects with incompletely explained chest pain given methacholine had neither ECG change nor spasm. [ncbi.nlm.nih.gov]

  • Heart Disease

    Twenty patients with chronic exertional angina, positive exercise test results and coronary heart disease were compared with 14 patients with variant angina and ST-segment elevation during an ergonovine test. [ncbi.nlm.nih.gov]

    Family history and genetics - Angina Ischemic heart disease often runs in families. Also, people who have no lifestyle-related risk factors can develop ischemic heart disease. [nhlbi.nih.gov]

  • Retrosternal Chest Pain

    Fifteen minutes after a renal arteriogram (May 7) was performed, the patient had severe retrosternal chest pain associated with hypotension and bradycardia. Serial ECGs are depicted [jamanetwork.com]

    Ahmed, MD, Iowa Heart Center, Jennie Edmundson Hospital, Council Bluffs, Iowa Typical anginal symptoms are characterized by recurrent attacks of retrosternal chest pain brought on by effort and emotion, and relieved by rest or by the administration of [cathlabdigest.com]

  • Shoulder Pain

    Angina may be more difficult to identify in some elderly people when they have symptoms such as abdominal pain after eating (due to increased blood demand for digestion) or have back or shoulder pain (which may be attributed to arthritis). [labtestsonline.org]

Further workup revealed metastatic pheochromocytoma. Conclusion Calcium channel blockers and nitrates which promotes coronary vasodilatation are commonly used in management of prinzmetal angina. [onlinejacc.org]

Hence, the coronary angiography is usually part of the workup of these patients and can help to guide the treatment4,6. Treatment Nitrates and calcium channel blockers are the main treatments for patients with variant angina. [scielo.br]

  • ST Elevation

    The mean daily number of ST elevation in group 1 was similar to that in group 2 (4.8 /- 5.1 vs 4.1 /- 4.6; p not significant). [ncbi.nlm.nih.gov]

    Associated with reversible ST elevations on ECG. Does not cause an increase in serum concentrations of cardiac biomarkers. [youtube.com]

    At the onset of this dangerous state an unusual ischemic ST elevation, the "Prinzmetal dome phenomenon," was seen. [annals.org]

  • T Wave Inversion

    wave inversion or flattening from previous MI Exercise ECG Thallium test Coronary angiography Exclude precipitating factors – anaemia, diabetes, hyperlipidaemia, thyrotoxicosis, GCA Management Change lifestyle Treat modifiable risk factors – hypertension [medicalnotesonline.blogspot.com]

    Once again, ECGs demonstrated T-wave inversion in V1–3. A repeat test showed that cTnI level was elevated at 0.4 ng/L. [smj.org.sg]

  • Ischemic Changes

    In the rest 201Tl study, septal perfusion was low on the early image, although partial redistribution of this site was observed on the delayed image without the appearance of chest pain or electrocardiographic ischemic change. [ncbi.nlm.nih.gov]

    They also demonstrate the importance of Holter monitoring (of 24–48 h) or loop recorders (depending on the frequency of symptoms) illustrating both ischemic changes and the ventricular arrhythmias caused by this ischemic environment. [tandfonline.com]

    The patient is considered to have “definite” vasospastic angina when ischemic change (ST elevation or ST depression of 0.1 mV or more) is clearly observed on the ECG during attacks or a positive finding of coronary spasm on coronary angiography ( 90% [journalofcardiologycases.com]

    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.[9] The primary cause of cardiac syndrome X is unknown, but factors apparently [en.wikipedia.org]

The frequency of anginal attacks and the consumption of sublingual nitroglycerin tablets decreased significantly in both treatment periods in comparison with those in the observation period before treatment, but in the observation period after treatment [ncbi.nlm.nih.gov]

CONCLUSIONS: Although the prognosis of multivessel spasm is believed to be poor, this may not necessarily be so. [ncbi.nlm.nih.gov]

Variant angina pectoris (VAP) is different to classical atherosclerotic AP in terms of etiology, treatment, and prognosis [ 1 Stern S. Bayes de Luna A. Coronary artery spasm: a 2009 update., ]. [internationaljournalofcardiology.com]

Conventional therapy including nitrates, beta blockers, and surgical bypass has proved to be generally unsatisfactory in patients with variant angina of suspected vasospastic etiology. [ncbi.nlm.nih.gov]

Description : • Angina caused by transient coronary spasms (usually occurring close to areas of coronary stenosis) • Unrelated to exertion and may even occur at rest (classically at night) Etiology : e.g., cigarette smoking, use of stimulants (e.g., cocaine [youtube.com]

The entity, “variant angina pectoris,” continues to be a controversial one in terms of definition, etiology, and management. [journal.chestnet.org]
