[Utility of pravastin in cardiac transplant dyslipidemia].

Patients undergoing cardiac transplantation are at increased risk of dyslipidemia (60% to 80%). Lipid-lowering treatment in these patients should be aggressive given the known role of dyslipidemia in chronic transplant rejection. The objective of this study was to evaluate the efficacy and safety of pravastatina therapy and its effect upon cyclosporine levels in a population of dyslipidemic cardiac transplant patients.A total of 20 cardiac transplant patients were enrolled in this 39-week length prospective observational study. Patients had serum cholesterol levels exceeding 200 mg/dl, and received pravastatin therapy at the adequate dose to obtain an optimal lipid profile without significant adverse effects. Pravastatin, at a mean dose of 50 18 mg/day, produced a significant reduction in total cholesterol levels (from 291 32 to 203 25 mg/dl, p < 0.05), LDL cholesterol (from 187 34 to 102 15 mg/dl, p < 0.05) and an increase in HDL-cholesterol levels (from 48 16 to 55 14, p < 0.05). A slight asymptomatic increase in CPK levels was observed but no differences in cyclosporine levels. Pravastatin has shown to be an effective and safe therapy in dyslipidemic cardiac transplant patients.

Left ventricular end-diastolic extrasystole with pseudonormalization of a left bundle branch block unmasking inferior ischemia.

An electrocardiogram tracing of a patient in conducted sinus rhythm with left bundle branch block is shown, in which occasional pseudonormalization of intraventricular conduction is seen. This event is attributed to ventricular fusions with end-diastolic extrasystoles of the left His-Purkinje system distal to the block site. This type of extrasystole is discussed. In this case, normalization of ventricular activation allowed for diagnosis of inferior subepicardial ischemia.

[Myocardial bridging as a cause of acute ischemia. Description of a case and review of the literature].

Myocardial bridges consist of muscle fiber bundles lining an epicardial coronary artery for a variable distance. They are a relatively common finding, with incidence changing on the basis of the study method used (angiographic/necropsy). Although myocardial bridges are usually associated with a benign prognosis, being in many cases asymptomatic and only found by chance, their presence has also been considered a cause of angina, malignant arrhythmia, myocardial infarction and sudden death. They are diagnosed in vivo by angiography when a systolic compression of a coronary artery which disappears during diastole is evidenced. We report the case of a patient with electrocardiographic signs of severe ischemia in the territory of the anterior descending artery, which was initially assessed as myocardial infarction and treated as such. Eventually, the ECG returned to normal, and no new Q waves of necrosis occurred. An angiohemodynamic study confirmed the existence of an isolated muscular bridge over the middle third of the anterior descending artery, with no other associated coronary lesions.

[Emergency implantation of intracoronary stent after acute occlusion of the common trunk of the left coronary artery].

Nowadays, the implantation of coronary endoprosthesis within the left main coronary artery is not considered as an absolute contraindication. Here, we show a case of acute occlusion within the left main coronary artery. This was resolved by implanting a stent during a programmed cardiac catheterization. It should be stressed that this problem was occurred without manipulating the left coronary tree. In addition, the patient was in cardiac arrest when the stent was implanted. Cardiopulmonary resuscitation was applied because of this condition.
