Cardiac autonomic impairment and chronotropic incompetence in fibromyalgia
INTRODUCTION We aimed to gather knowledge on the cardiac autonomic modulation in patients with fibromyalgia (FM) in response to exercise and to investigate whether this population suffers from chronotropic incompetence (CI). METHODS Fourteen women with FM (age: 46 ± 3 years; body mass index (BMI): 26.6 ± 1.4 kg/m2) and 14 gender-, BMI- (25.4 ± 1.3 kg/m2), and age-matched (age: 41 ± 4 years) h...
متن کاملChronotropic incompetence in heart failure.
The relationship between heart rate (HR) during exercise and exercise capacity in patients with heart failure due to left ventricular systolic dysfunction remains unclear. The accepted diagnostic criterion for chronotropic incompetence (CI), a maximum agepredicted heart rate (MA-PHR) 85%, is seen in 50% of patients with severe heart failure on contemporary medical therapy (1). Whether the lesse...
متن کاملChronotropic incompetence and autonomic dysfunction in patients without structural heart disease.
AIMS An attenuated heart rate response to exercise, termed chronotropic incompetence (CI), has been reported to be an independent predictor of cardiovascular mortality. We examined the change in autonomic function during exercise testing and correlated the results with CI. METHODS AND RESULTS Exercise testing using a bicycle ergometer was performed in 172 patients who had no evidence of cardi...
متن کاملChronotropic Incompetence in Diabetic Elderly on Echocardiography
For practical purpose, most studies define CI as the incapacity to reach 80% of heart rate (HR) reserve according to the formula: HR reserve = (peak HR – resting HR) / (maximum HR – resting HR) x 100. It has been suggested that the definition of CI should be assessed when the diagnostic method uses positive inotropic drugs to induce HR increase. It is necessary to better understand which practi...
متن کاملChronotropic incompetence: a never-ending story.
A clear association between chronotropic incompetence and increased mortality has been established by a variety of studies in patients with coronary artery disease as well as in healthy individuals. These results gave rise to speculation that rate responsive stimulation might improve prognosis in pacemaker (PM) patients with concomitant chronotropic incompetence. To date, however, no study was ...
