We reviewed the clinical characteristics and outcome of cases of acute myocardial infarction occurring from January 1, 1985, through December 31, 1987, in the population of a long-term care institution for the elderly. The total number of patients in the series was 43. Comparisons were made between those patients transferred to a general acute-care hospital and those who remained at the facility. The most common initial symptoms of acute myocardial infarction in 32 of 48 patients were, in order, dyspnea, dizziness or syncope, precordial pain, and abdominal pain. Nine (of 43) patients were asymptomatic. In the 14 (of 43) patients transferred to an acute-care hospital, cardiac failure, arrhythmias, and cardiogenic shock were much more frequent than among those retained in the long-term care facility. We concluded that a high index of suspicion for the diagnosis of acute myocardial infarction in the institutionalized elderly is indicated. Patients with mild infarction can be retained in long-term care institutions; resulting mortality from cardiac disorders should be low in adequately staffed and equipped long-term care institutions.

We describe a case of coronary-subclavian steal syndrome treated with percutaneous transluminal angioplasty. A 58-year-old female who had her first coronary bypass operation 6 years previously and a second operation 3 years previously involving the left internal mammary artery and right gastroepiploic artery, developed unusual angina on effort characterized by left precordial pain, pain in the left shoulder and arm, tinnitus and dizziness. Angiography revealed retrograde flow to the left subclavian artery via the left vertebral artery and left internal mammary artery. Severe stenosis of the left subclavian artery was demonstrated at its ostium. Restoration of antegrade flow to the vertebral artery and left internal mammary artery by transluminal angioplasty resulted in complete resolution of these symptoms.

The results of many studies on the prevalence of mitral valve prolapse have been greatly influenced by the diagnostic methods and criteria adopted as well as by population selection. The method of choice today is 2d-echocardiography because of its ability to highlight both movement anomaly (i.e. functional prolapse) and any eventual morphological variations of the mitral valve (i.e. anatomic prolapse). The latter (chordae lengthening, thickening and overabundance of the leaflets, dilation of the valvular ring) are, nowadays, considered especially important even as predictive factors of complications. Therefore we studied the prevalence of these two types of prolapse in a population of 420 university students. Functional mitral valve prolapse was found in 27/420 (6.4%) and anatomical prolapse in 2 cases (0.5%). No auscultatory finding was present in 24/27 patients with functional prolapse. There was no correlation between the two types of mitral valve prolapse and the body mass index, the fractional shortening of the left ventricle and symptoms (dyspnea, palpitations, precordial pain, dizziness). We think that the distinction between the two types of mitral valve prolapse should prove very useful for the comparison of results in future epidemiological studies. Follow-up of both groups of patients will hopefully clarify the usefulness of such distinction from the clinical point of view.

From the district Haarlem-Noord, 558 patients suffering from an acute myocardial infarction (AMI) were admitted in the years 1982 through 1985. Of these patients 62.9% was 65 years or older, 63.6% was male. The chance of getting an AMI was 8 times greater for the elderly than for younger people, which is in agreement with figures in the whole country. The most important feature--precordial pain--was less frequent in the elderly, i.e. 63.8% compared to 87% for younger people. However, the elderly suffered more from less specific symptoms as breathlessness, heartfailure, dizziness, syncope, neurological and psychiatric symptoms. The frequency of these symptoms varied from 4.5 to 30%. This is 2 to 5 times higher than for people younger than 65 years old. The mortality rate was 31% for people older than 65 years. This was significantly higher than the rate for younger patients (7.7%).

White woman, 31 years old, complaint pain in the left arm, at rest, and few months later she had pain in the precordial region with dyspnea, diaphoresis and dizziness without any inducing factor. One hour later, symptoms ceased spontaneously, remaining daily precordial pain. Subsidiary examinations as cineangiocoronariography revealed 100% of arterial lumen constriction in the middle portion of the descending coronary artery, during systole, as well as in the diagnoalis and marginal branches. Multiple myocardial coronary bridges has been described in necropsy, but during cinecoronarioangiography, this case appeared to be the first one.

Paroxysmal supraventricular tachycardia (SVT) may have numerous electro-physiologic mechanisms. The most common type of SVT is AV-nodal reentry tachycardia (60%) followed by the bypass tract-mediated SVT (preexcitation. 30%) and a smaller group (10%) comprising paroxysmal atrial flutter or fibrillation and atrial ectopic tachycardia. In persons with otherwise normal hearts symptoms are usually mild and include palpitations or an uneasy feeling in the chest. But some describe precordial pain. Weakness, dizziness, nausea, vomiting, and even syncope. Whenever possible a 12-lead-ECG during an episode of SVT should be obtained. If not possible the use of several Holter-ECG or of an event-recorder may be helpful. Conversion of a SVT can be accomplished by vagal maneuvers or intravenous adenosine (6-18 mg bolus injection). Further diagnostic procedures should prove or rule out a significant structural heart disease. Therapeutic options (expectative, pharmacological prophylaxis, invasive electrophysiologic testing and catheter-mediated modification or ablation) are chosen according to the objective threat (e.g. ventricular fibrillation due to 1:1 conducted atrial fibrillation in a preexcitation syndrome) and the subjective complaints. Definitive healing of the AV-nodal reentry tachycardia and the bypass tract-mediated SVT can be achieved by use of catheter-mediated modification or ablation in 95 to nearly 100%.
