OBJECTIVES This study was performed to investigate the long-term outcome of patients with unstable angina within subgroups of the Braunwald classification. BACKGROUND Long-term follow-up studies of patients with unstable angina are rare and date from more than two decades ago. This study was performed to establish the prognosis of different subgroups of patients with unstable angina (Braunwal...

Coronary angioplasty was performed in 53 patients in whom unstable angina had reoccurred after 48 hr and within 30 days after sustained myocardial infarction. Single-vessel disease was present in 64% of the patients and multivessel disease in 36%. The preceding myocardial infarction had been small to moderate in size in the majority of the patients. The left ventricular ejection fraction was mo...

We investigated the prognostic significance of new-onset angina in patients in whom coronary anatomic characteristics were known. New onset angina was defined as angina of less than 3 months duration. Consecutive patients (n = 1727) with significant coronary artery disease (diagnosed at cardiac catheterization) and who had not had a prior myocardial infarction or congestive heart failure were s...

introduction: unstable angina as a clinical condition includes a major group of patients manifested with acute coronary syndrome. misdiagnosis of this clinical syndrome causes myocardial infarction (mi) and death. conventional and advanced forms of treatment are used with the aim of rapid stabilization of unstable angina. although infusion of glucose - insulin - potassium (gik) solution has had...

The frequency and type of acute lesions in the four major (right, left main, left anterior descending, left circumflex) epicardial coronary arteries were examined at necropsy in 14 patients with unstable angina pectoris, 21 patients with sudden coronary death and 32 patients with a fatal first acute myocardial infarction. None of the 67 patients had a grossly visible left ventricular scar (heal...

BACKGROUND Endothelin is an extremely potent vasoconstrictor that may have a role in the pathogenesis of acute myocardial ischaemia. Atrial natriuretic factor is an endogenous antagonist of endothelin. To find the pattern and possible importance of circulating endothelin in ischaemic heart disease, concentrations in normal controls and those in patients with stable and unstable angina, acute my...

The prevalence of microvascular angina is estimated to be up to 30% of stable angina patients with nonobstructive coronary arteries. 19% of women presenting with acute coronary syndrome, 30% of women presenting with unstable angina, 9.1% of women with non-ST-elevation myocardial infarction and 10% of women with ST-elevation myocardial infarction were determined to have normal or non-obstructive...

OBJECTIVES We examined whether angina pectoris occurring shortly before the onset of acute myocardial infarction can actually preserve postischemic left ventricular function in humans. BACKGROUND Experimental studies indicate that brief, transient episodes of ischemia render the heart very resistant to infarction from a subsequent sustained ischemic insult, an effect termed ischemic precondit...

The monorail technique allows monitoring of all steps of the coronary angioplasty procedure by high quality coronary angiography; easy, rapid, and safe recrossing and redilatation of the lesion if necessary; and stepwise dilatation of a stenosis with sequential increase of size of balloons. Transstenotic pressure differences cannot, however, be measured through the narrow shaft of the standard ...
