Butane-induced acute global myocardial ischemia without coronary artery pathology.

The case report describes a case of acute myocardial ischemia precipitated by propane butane inhalation. The dependency of this substance around the world is still moderate but is increasing due to the easy availability of the substance and the facility with which the effects can be concealed. The toxicity of the substance is significant; affecting the heart, the brain and the liver.

Primary angioplasty in acute myocardial infarction with right bundle branch block: should new onset right bundle branch block be added to future guidelines as an indication for reperfusion therapy?

Aims: The current guidelines recommend reperfusion therapy in acute myocardial infarction (AMI) with ST-segment elevation or left bundle branch block (LBBB). Surprisingly, the right bundle branch block (RBBB) is not listed as an indication for reperfusion therapy. This study analysed patients with AMI presenting with RBBB [with or without left anterior hemiblock (LAH) or left posterior hemiblock (LPH)] and compared them with those presenting with LBBB or with other electrocardiographic (ECG) patterns.

Typical electrocardiographic deviations after cessation of physical activities in elite sportsmen.

We observed that ECG changes associated with high levels of sporting activity are reversible in the majority of cases after cessation of the sports career. This is probably related to the normalization of the raised vagal tone and diminution of the effort-related heart hypertrophy and chamber dilatation in ex-sportsmen. The persistent ECG changes observed in some of the ex-sportsmen could be related to the ageing processes observed in the general population as well.

Ageing of ex-sportsmen: ergonometric parameters of ex-elite athletes.

After the cessation of physical activity for six or more years, processes start to occur in previously active sportsmen that cause aerobic capacity to reach the values observed in people of the same age who have never participated in sport. However, the physical capacity of these people remains above the average level for the same age group. The important factors related to the aerobic capacity of ex-elite sportsmen are the age, current physical activity and body weight.

Isolated bilateral ostial coronary stenosis with proximal right coronary artery occlusion.

The incidence of coronary ostial stenosis in patients undergoing coronary arteriography has been found to range between 0.07 and 0.25%.

Diagnosis and Management of Complicated Left Atrial Mural Endocarditis: The Role of Transesophageal Echocardiography.

Mural endocarditis that involves the left atrial wall is rare. We report on the transesophageal findings in a patient with left atrial mural endocarditis and discuss its recognition, complications, and treatment.
