Differences in the cardiovascular hemodynamic response between the Valsalva and Reverse Valsalva Maneuvers in healthy subjects.

Background: The Valsalva Maneuver (VM) is the first-line treatment for paroxysmal supraventricular tachycardia, but a recent, novel, and efficient tool to restore sinus rhythm has been described, i.e., the Reverse Valsalva (RV).

The autonomic nervous system in anorexia nervosa - an implication for the fat tissue.

Eating disorders are a heterogeneous group of diseases affecting mainly young people in developed countries. Among them, anorexia nervosa (AN) is the one with the highest mortality, up to five times higher compared to healthy individuals. The etiology of this medical condition is complex and still un- certain.

Microvascular angina (Cardiac Syndrome X) from a historical overview, epidemiology, pathophysiology to treatment recommendations - a minireview.

Microvascular angina (MVA) is a condition characterized by the presence of angina-like chest pain, a positive response to exercise stress tests, and no significant stenosis of coronary arteries in coronary angiography, with absence of any other specific cardiac diseases. The etiology of this syndrome is still not known and it is probably multifactorial. Coronary microvascular dysfunction is proposed as the main pathophysiological mechanism in the development of MVA.

Past strong experiences determine acute cardiovascular autonomic responses to acoustic stress.

Background: Stress is a major risk factor for cardiovascular (CV) disease. We hypothesized that past strong experiences might modulate acute CV autonomic responses to an unexpected acoustic stimulus. A i m: The study's aim was to compare acute CV autonomic responses to acoustic stress between students with and without a past strong experience associated with the acoustic stimulus.

[The blood gas status in bitches with pyometra-endometritis complex].

The blood gas status of 52 bitches presented with pyometra-endometritis complex was examined. Nine healthy bitches with a normal sexual cycle served as control group. Depending on the clinical symptoms, the sick bitches were divided into two groups (A and B).
