Reduced cardiopulmonary baroreflex sensitivity in patients with hypertrophic cardiomyopathy.
OBJECTIVES We sought to assess baroreflex function in patients with hypertrophic cardiomyopathy (HCM). BACKGROUND We have previously demonstrated a specific abnormality in the afferent limb of the cardiopulmonary baroreflex in patients with vasovagal syncope. Patients with HCM exhibit abnormal control of their vasculature during exercise and upright tilt; we therefore hypothesize a similar ab...
متن کاملCardiopulmonary Exercise Testing and Prognosis in Hypertrophic Cardiomyopathy.
BACKGROUND Exercise testing is performed in patients with hypertrophic cardiomyopathy to evaluate blood pressure response, a risk factor for sudden cardiac death. The prognostic role of exercise gas exchange variables is unknown. METHODS AND RESULTS Between 1998 and 2010, 1898 patients (age 47±15 years, range 16-86 years; 67% male) with hypertrophic cardiomyopathy underwent cardiopulmonary ex...

متن کاملDIFFUSE CORONARY ARTERIAL ECTASIA WITH HYPERTROPHIC CARDIOMYOPATHY
A 40 year old male, a known case of hypertrophic cardiomyopathy, was admitted for catheterization. At catheterization and angiography, septum was hypertrophied to about 5cm and diffuse coronary artery aneurysm was revealed. We found no previous report of coronary artery aneurysm in hypertrophic cardiomyopathy.

Circulation Research is available at http://circres.ahajournals.org DOI: 10.1161/CIRCRESAHA.117.311059 Abstract: Hypertrophic cardiomyopathy (HCM) is a genetic disorder that is characterized by left ventricular hypertrophy unexplained by secondary causes and a nondilated left ventricle with preserved or increased ejection fraction. It is commonly asymmetrical with the most severe hypertrophy in...
