[Massive pulmonary embolism without echocardiographic features of right ventricular overload].

A case of 70-year-old patient with massive pulmonary embolism confirmed in CT, but without changes in right ventricle size and function in echocardiography is presented. This case is consistent with literature data that echocardiography has relatively low sensitivity in the diagnosis of acute pulmonary embolism.

[Pathogenesis and treatment of acute coronary syndromes].

Acute coronary syndromes (ACS) include unstable angina and non-ST elevation myocardial infarction (UA/NSTEMI) and ST-segment elevation myocardial infarction (STEMI). Acute coronary syndromes lead to important epidemiological and economical problems. In polish population an estimated incidence of ACS is 250 000 cases per year.

Age-adjustment of HRV measures and its prognostic value for risk assessment in patients late after myocardial infarction.

The Aims Of Our Study Were: (1) to establish the normal limit of the heart rate variability (HRV) indices in a healthy population and in its four age-related subgroups, including a new HRV index, HRV fraction; and (2) to analyse the frequency and predictive value of abnormally low HRV in a population of post-infarction patients in respect to the cut-points chosen (raw or age-adjusted).

Methods: Normal population of 296 healthy subjects (81 f, 215 m, aged 47+/-10 years) and post-infarction population of 298 patients (>3 months after acute MI, 65 f, 233 m, aged 56+/-10) were examined. The normal population was divided into 4 subsets based on age at entry: <35, 35-44, 45-54 and >54 years.
