Effects of Sauna Alone and Postexercise Sauna Baths on Blood Pressure and Hemodynamic Variables in Patients With Untreated Hypertension

J Clin Hypertens (Greenwich). 2012;00:00–00 ©2012 Wiley Periodicals, Inc. The effects of sauna alone vs exercise and sauna on ambulatory blood pressure monitoring and central hemodynamic variables were measured in 16 patients with untreated hypertension assigned to a control period, sauna, or exercise and sauna. Exercise and sauna had positive effects on 24‐hour systolic and mean blood pressure in patients with untreated hypertension. Exercise and sauna and sauna alone reduce total vascular resistance, with positive effects lasting up to 120 minutes after heat exposure.     

Chronic total occlusion:To treat or not to treat

Over the last two decades,there has been increasing interest in new techniques for the percutaneous treatment of coronary chronic total occlusions(CTO),which have a success rate that is much higher than that of a few years ago.The rise in percutaneous treatment for these lesions is due to its ability to improve the symptoms and prognosis of patients in the chronic and stable phase of coronary disease.Current data suggest that successful percutaneous coronary intervention for CTO is associated with improvement in patient symptoms,quality of life,left ventricular function,and survival,compared with those with unsuccessful CTO PCI.However,all the scientific evidence supporting this treatment comes from observational studies,and no randomized study comparing percutaneous treatment with medical treatment has yet been published.A major limitation of these studies is their observational design,with limited information with regard to potential baseline differences between the successful vs unsuccessful cohorts.Pending randomized studies,patients should be selected very carefully,especially if they are asymptomatic or very few symptoms,and the benefits obtained in terms of complications during the procedure,the quality of life obtained and further ischemic events avoided should be evaluated systematically.In this review,we will consider the available information supporting percutaneous treatment for chronic occlusions,as well as the areas of uncertainty where more research projects are required.
