Sex and age differences and outcomes in acute coronary syndromes.

Background: There is conflicting information about sex differences in presentation, treatment, and outcome after acute coronary syndromes (ACS) in the era of reperfusion therapy and percutaneous coronary intervention. The aim of this study was to examine presentation, acute therapy, and outcomes of men and women with ACS with special emphasis on their relationship with younger age (≤65years).

Methods: From January 2010 to June 2015, we enrolled 5140 patients from 3 primary PCI capable hospitals.

Predictive value of biphasic response during dipyridamole echocardiography test in the low-risk group of patients after acute myocardial infarction.

To investigate whether biphasic response during dipyridamole echocardiography test (DET), which represents viable but potentially ischemic myocardium in the infarcted region, affects prognosis of patients after uncomplicated acute myocardial infarction, we performed high-dose DET in 80 consecutive patients younger than 65 years with first acute myocardial infarction and preserved left ventricular function. Patients were followed up for 27 +/- 12 months for new coronary events. According to DET results all patients were classified into 4 groups: group 1 consisted of 20 patients with biphasic response; group 2 included 14 patients with sustained improvement in regional contractility; group 3 consisted of 24 patients showing no change in contractility; and group 4 included 22 patients with worsening response.

Effects of glucose-insulin-potassium infusion on ST-elevation myocardial infarction in patients treated with thrombolytic therapy.

The role of glucose-insulin-potassium (GIK) infusion in the management of acute myocardial infarction is not well established. This prospective, randomized study comprised 120 patients who had ST-elevation myocardial infarction that was treated within 12 hours from symptom onset with a high dose of GIK (25% glucose, 50 IU of soluble insulin per liter, and 80 mmol of potassium chloride per liter at 1 ml/kg/hour over 24 hours) as adjunct to thrombolytic therapy (1.5 MU of streptokinase/30 to 60 minutes; GIK group) or thrombolytic therapy alone (control group).

Common form of Lyme borreliosis carditis--complete heart block with syncope: report on 3 cases.

Third degree atrioventricular (AV) heart block with severe Adams-Stokes attacks in 3 patients with Lyme borreliosis is described. All patients had similar clinical manifestations: previously healthy, they experience syncope as an abrupt onset of the disease. Data on skin changes--erythema migrans--was subsequently obtained, although the patients did not recall being bitten by a tick.
