To evaluate the feasibility of prehospital thrombolysis in Sweden in terms of safety and to examine the various components of the delay between onset of symptoms and start of treatment. ⋯ Implementation of prehospital thrombolysis on a national basis in Sweden appears to be safe. More than half the patients can be given treatment less than 2 h after the onset of symptoms. There is potential for reducing this time still further.

Comparative Study
Outcomes of patients presenting with acute coronary syndromes and negative Troponin-T.
The aim of the study was to compare need for revascularization and clinical course between troponin-positive and troponin-negative patients with unstable angina pectoris defined as class IIIB according to Braunwald classification. ⋯ In patients with unstable angina in class IIIB according to Braunwald classification, the negative cardiac troponin test did not exclude severe coronary artery disease, which in the majority of patients required revascularization without any additional non-invasive testing for ischemia. Therefore, we postulate that patients with clinically evident unstable angina (IIIB) should be referred to early invasive assessment despite negative troponin T screening.

Comparative Study
The influence of age on gender-specific differences in the left ventricular cavity size and contractility in patients with hypertrophic cardiomyopathy.
The aim of the study was to assess gender-specific differences in left ventricular cavity size, contractility and left ventricular outflow tract obstruction in younger and older subgroups of patients with hypertrophic cardiomyopathy. ⋯ In patients with hypertrophic cardiomyopathy, the gender-based differences in the absolute value of left ventricular cavity size persisted with aging. In older females left ventricular contractility was higher and left ventricular outflow tract gradient occurred more frequently than in males. In younger patients with hypertophic cardiomyopathy these sex-based differences were absent. The gender-specific differences in the parameters of left ventricular systolic function became apparent with increasing age.
