Acute effects of continuous positive airway pressure on cardiac sympathetic tone in congestive heart failure.

abstract：BACKGROUND:The World Health Organization aims to reduce mortality from chronic diseases including cardiovascular disease (CVD) by 25% by 2025. High blood pressure is a leading CVD risk factor. We sought to compare 3 strategies for treating blood pressure in China and India: a treat-to-target (TTT) strategy emphasizing ...
