cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Obstructive Sleep Apnea and Atrial Arrhythmogenesis

Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with relevant morbidity and mortality. Besides hypertension, valvular disease and cardiomyopathy, mainly ischemic and dilated, also other conditions like obesity, alcohol abusus, genetic factors and obstructive sleep apnea (OSA) are discussed to contribute to the progression from paroxysmal to persistent AF. The ...

Environmental epidemiology: An introduction

[Epidemiology of atrial fibrillation].

UNLABELLED FREQUENCY: Atrial fibrillation is the most frequent sustained arrhythmia, especially in the elderly. The incidence accounts for 2% past the age of 40 years, 6% over 70, an approximately 15% over 90 years old. PATHOGENESIS Primary cause in "idiopathic" atrial fibrillation is differentiated from secondary causes of cardiac and non-cardiac origin. Important predictive cardiovascular d...
