, coronary artery balloon angioplasty, accelerating angina, new-onset angina, angina, unstable, progressive angina, unstable angina describes a syndrome that is intermediate between stable angina, myocardial infarction, heart attack, characterized, accelerating, "crescendo" pattern of chest pain that lasts longer than in stable angina, occurs at rest, less exertion than in stable angina, less responsive to medication, unstable angina, myocardial infarction, considered acute coronary syndromes, stable angina, chronic condition, unstable angina occurs in approximately 6 out of every people, coronary artery disease, due to atherosclerosis is by far the most common cause of unstable angina, a coronary artery spasm, rare cause of angina, initially, narrowing, form of atheroschlerotic plaques, the coronary arteries severe enough to cause stable angina, exertion, stress, narrowing, causes, no symptoms at, reasons, not well understood, plaques reach a point at which they rupture, under these circumstances, a plug formed by platelets, blood clots, form, causing an already narrowed blood vessel to, become highly susceptible to becoming completely blocked, unstable situation, progress to complete blockage, the vessel, followed by heart attack, once this type of lesion exists, coronary artery, whether the event leads to a heart attack, chest pain produced by the extreme narrowing, the coronary artery, become unstable, unlike stable angina, chest pain, induced by exercise, stress, chest pain in unstable angina, occur at rest, precipitating factors, pain, increase in severity, frequency, duration at low levels of activity, no identifiable reason, type of angina, occur soon after a heart attack, risk factors, unstable angina, similar to those, stable angina, coronary artery disease, male gender, cigarette smoking, high cholesterol levels, in particular, high ldl cholesterol, low hdl cholesterol, high blood pressure, diabetes, family history of coronary heart disease, age 55, sedentary lifestyle, than 30% over ideal body weight, sudden overwhelming stress, precipitate an episode of angina, typical anginal pain, originates, in the chest, radiate, shoulder, arm, jaw, neck, areas, pain, described, tightness, squeezing, crushing, burning, choking, aching, unstable angina is differentiated from stable angina in that the pain, occur at rest, new in conditions of onset, last longer than previous anginal attacks, less responsive to medication, in other words, a pattern of stable angina has been present previously, development of unstable angina defined by a change, in the pattern, frequency, severity, the pain, a pattern of stable angina has not been present previously, beginning of chest pain episodes also constitutes unstable angina, physical examination, reveal a change in blood pressure, transient heart murmur, arrhythmias, irregular heartbeats, ecg changes that occur at rest, pain, diagnostic, heart scans, coronary angiography, the heart, echocardiography, reveal changes, in the heart, decreased coronary blood flow, blood tests cpk, cpk-mb, troponin i, troponin t, myoglobin, diagnose unstable angina, predict likelihood of progression to heart attack, an individual experiencing unstable angina, rest, hospitalization, prevent complications, a cornerstone of therapy, unstable angina is antiplatelet medication, prevent platelet aggregation, initial event, in the blood circulation clot formation, a vessel, one antiplatelet agent widely used is aspirin, a medication, clopidogrel has shown in clinical studies to be more effective than aspirin in reducing the likelihood of heart attacks, clopidogrel, aspirin used together, often administered, heart attacks, heparin, nitroglycerin, unstable angina, sublingually, under the tongue, intravenously, iv, medications include beta-blockers, calcium channel blockers, anti-anxiety medications, medications to control blood pressure, abnormal heart rhythms, surgery recommended, cabg, coronary artery bypass grafting, ptca, balloon angioplasty, the implantation of a stent, depending on many factors, most important factor, severity, the underlying coronary artery disease, factors include the severity, the episode, past history of heart attack, number of medications a patient was taking, the episode began, associated arrythmias, heart attacks, cause sudden death, complications of unstable angina include progression to an acute myocardial infarction, heart attack, any, the symptoms described, above appear, best prevention of unstable, stable angina, modify those risk factors, changed, stop smoking, lose weight, overweight, control blood pressure, diabetes, cholesterol, in fact, modifying risk factors, prevent the progression, of arterial blockages, lead to decrease, in the severity of blockages, aspirin, antianginal medications nitrates, nitroglycerin, beta-blockers, calcium channel blockers, others, prevent the occurrence of angina, lessen its severity, aspirin, clopidogrel, reduce the likelihood of heart attacks in predisposed patients.
