- Abstract
Obstructive sleep apnea (OSA) is an independent risk factor for hypertension and cardiovascular disease. OSA is the frequent underlying disease of secondary hypertension and resistant hypertension. In 2003, the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure recognized sleep apnea as a common and identifiable cause of hypertension and suggested blood pressure screening among patients with OSA. OSA increases both daytime and nocturnal ambulatory blood pressures through the activation of various neurohumoral factors including the sympathetic nervous system and the renin-angiotensin-aldosterone system. Randomized, controlled trials have evaluated the use of continuous positive airway pressure (CPAP) to reduce BP among persons with OSA. The benefits of OSA treatment are related to implications for hypertension management. more...

- Abstract
Obstructive sleep apnea (OSA) is strongly associated with hypertension. The seventh report of the joint national committee (JNC-VII) guidelines have placed OSA at the top of the list to induce secondary hypertension. Severe OSA patients revealed the high prevalence of hypertension. Compared with normal subjects, patients with OSA had a higher 24-hour blood pressure, especially nighttime blood pressure. More recently, prospective data showed that sleep apnea syndrome was an independent risk for onset of hypertension. There is a lot of evidence that demonstrates that treating OSA using continuous positive airway pressure (CPAP) is an effective for management of OSA. more...

- Abstract
Objectives: The relations between muscle strength, muscle endurance, and cardiopulmonary parameters were investigated in patients with chronic heart failure., Methods: The subjects comprised 33 outpatients with stable chronic heart failure (27 men, 6 women, mean age 60.3 +/- 12.7 years). A pedal-type isokinetic device was used throughout the study. The safety of the study protocol was examined first. Maximum muscle power (peak power), an index of muscle strength, was measured for 6 consecutive revolutions(3 revolutions of each leg). The strength decrement index (SDI) was measured for 20 consecutive maximal revolutions (10 revolutions in each leg). The SDI is an index of muscle endurance and compares the mean power for revolutions 9 and 10 with that for revolutions 2 and 3. Each subjects underwent symptom-limited cardiopulmonary exercise testing with a cycle ergometer on another day., Results: No subject experienced continuous abnormal heart rate or blood pressure response, chest pain, ischemic ST-T change, or severe arrhythmia. The peak power and the SDI were correlated with the anaerobic threshold (r = 0.42, 0.52, respectively), with peak oxygen uptake (r = 0.66, 0.61), and with the increase in oxygen uptake per unit increase in work rate (r = 0.43, 0.63). However, the slope of the ventilation equivalent to carbon dioxide output was correlated only with the SDI (r = -0.54) and the time constant for the oxygen uptake decrease was correlated only with the peak power (r = -0.46)., Conclusions: Peak functional capacity depends on both muscle strength and endurance, and subjective symptoms in daily activity, especially dyspnea on exertion, depend mainly on muscle endurance in patients with chronic heart failure. more...

- Abstract
Objectives: To develop a measure for disease-specific health-related quality of life in patients with heart failure and examine its reliability and validity., Methods: One hundred and four patients with stable chronic heart failure (74 males, 30 females, mean age 64.2 +/- 10.0 years) with left ventricular ejection fractions of less than 40% were enrolled in this study. Each patient responded to the Medical Outcomes Study Short Form 36 (SF-36) and a disease specific questionnaire comprising four categories (dyspnea, sleep, appetite and fatigue), each consisting of five to six questions. A stepwise exploratory factor analysis was applied to the disease-specific measure to consider categorical fitness. In 25 of the 104 patients, the data in the questionnaire were compared with peak oxygen uptake, anaerobic threshold, slope of the regression line relating the ventilatory equivalent to carbon dioxide output (VE/VCO2 slope) and peak work rate. Correlations between the questionnaire and eight components of SF-36 were evaluated., Results: The appetite category proved unreliable and was excluded from consideration, so 12 questions were adopted from the other three categories. Cronbach's a values ranged from 0.68 to 0.89 and the coefficients of test-retest were from 0.84 to 0.94, so both internal consistency and reproducibility of these questions were considered excellent. The scores of three categories well reflected the severity of heart failure based in New York Heart Association functional class. The anaerobic threshold (r = 0.53), peak oxygen uptake (r = 0.66), VE/VCO2 slope (r = -0.48) and peak work rate (r = 0.41) correlated with the total score of the 12 questions. The total scores were closely correlated with the eight components of SF-36., Conclusions: This study suggests that the disease-specific questionnaire is applicable to evaluation of the health-related quality of life in patients with heart failure. more...

- Abstract
Objectives: Physical training in cardiac patients can increase exercise capacity and reduce plasma brain natriuretic peptide(BNP) concentration, but these effects may depend on the etiology of cardiac disease. The change in exercise capacity and BNP during the training period were investigated in patients with different cardiac diseases., Methods: Ninety-one patients after coronary artery bypass grafting(CABG) and 78 patients after valve replacement (VR) underwent a symptom-limited incremental cardiopulmonary exercise test before (1 month) and 6 months after physical training. Anaerobic threshold and peak oxygen uptake(peak-Vo2) were measured during the cardiopulmonary exercise test. Before each cardiopulmonary exercise test, a blood sample was obtained in the resting condition for measuring BNP., Results: Anaerobic threshold and peak-Vo2 were increased significantly from 1 month to 6 months in both groups. BNP in the CABG group indicated a tendency to decrease (194.6 +/- 155.3-->144.2 +/- 232.2 pg/ml, p < 0.1) from 1 month to 6 months. BNP in VR group was significantly decreased (159. 9 +/- 115.5-->112.8 +/- 131.7 pg/ml, p < 0.05) during the training period. The CABG group showed a significant negative correlation between peak-Vo2 and BNP at 1 month(r = -0.28, p < 0.01) and at 6 months(r = -0.39, p = 0.001). The VR group showed a significant negative correlation between peak-Vo2 and BNP at 6 months(r = -0.32, p < 0.01), but not at 1 month., Conclusions: Six months of physical training in patients after cardiac surgery may improve exercise capacity and reduce BNP. BNP concentration in the VR group before physical training did not reflect functional capacity. more...

- Abstract
Objectives: This study investigated whether myocardial infarction patients with diabetes mellitus had lower heart rate reserve to exercise by measuring the increment in heart rate (HR) divided by the increment of norepinephrine (NE) concentration from rest to peak exercise (delta HR/log delta NE). The difference in exercise training effects was also investigated., Methods: The 148 patients after myocardial infarction were divided into two groups, the DM group (n = 34) and the non-DM group (n = 114). Cardiopulmonary exercise testing was performed in each subject at 1 and 3 months after the onset. Blood samples were taken at rest and immediately after peak exercise, rest brain natriuretic peptide, rest and peak norepinephrine were analyzed. Exercise training was performed from 1 to 3 months after the onset., Results: Resting heart rates were significantly higher in the DM group than in the non-DM group both at 1 and 3 months although peak heart rates were not significantly different. Peak oxygen uptake were lower in the DM group both at 1 and 3 months after onset of myocardial infarction compared to the non-DM group. End-tidal carbon dioxide pressure was lower and the rate of increase of minute ventilation to carbon dioxide output was higher in the DM group. Plasma brain natriuretic peptide was higher in the DM group. delta HR/log delta NE was 19.4 +/- 4.0 in the DM group and 22.2 +/- 5.6 in the non-DM group (p < 0.01), and increased in only the non-DM group. delta HR/log delta NE was more closely correlated with peak oxygen uptake in the DM group than in the non-DM group., Conclusions: Impaired response to exercise training may be caused, in part, by impaired heart rate reserve to exercise in patients with diabetes mellitus. more...
