RESUMEN

The present study investigated the use of complementary and alternative medicine (CAM) and its relationship with health-related quality of life (HRQOL) in patients with type 2 diabetes mellitus. A total of 421 patients with type 2 diabetes mellitus who completely met the inclusion criteria, aged 67.3 ± 12.8 years, among 622 outpatients were recruited in this cross-sectional study. We examined the use of CAM, such as supplements, Kampo, acupuncture, and yoga. HRQOL was assessed by EuroQOL. A total of 161 patients (38.2%) with type 2 diabetes mellitus used some type of CAM. The use of supplements and/or health foods was the highest among CAM users (112 subjects, 26.6%). HRQOL was significantly lower in patients who used some CAM (0.829 ± 0.221) than in those without any CAM use (0.881 ± 0.189), even after adjustments for confounding factors [F(1, 414) = 2.530, p = 0.014]. Proper information on CAM is needed for patients with type 2 diabetes mellitus.

RESUMEN

PURPOSE: This open-label controlled study compared the therapeutic efficacy of three representative angiotensin II receptor blockers (ARBs) in hypertensive patients with type 2 diabetes attending a hospital outpatient clinic. The primary measure in this study was morning home blood pressure (BP). PATIENTS AND METHODS: Two studies were done concurrently to investigate the effects of switching from two different ARBs to olmesartan. Patients prescribed candesartan (8 mg once daily in the morning) or telmisartan (40 mg once daily in the morning) for 16 weeks were switched to olmesartan (20 mg once daily in the morning) for 16 weeks. Then, they were switched back to candesartan (CO group) or telmisartan (TO group) for another 16 weeks. RESULTS: Data from all patients in the CO group (n=165) and the TO group (n=152) were analyzed. Clinic and morning home BP and urinary albumin levels showed a significant decrease from baseline at 16 weeks after switching to olmesartan in both the CO and the TO group (clinic BP, morning home diastolic BP, and urinary albumin, P<0.05; morning home systolic BP, P<0.01). In contrast, clinic BP, morning home BP, and urinary albumin were significantly increased again 16 weeks after switching back to candesartan or telmisartan (clinic BP, morning home diastolic BP, and urinary albumin, P<0.05; morning home systolic BP, P<0.01). No subjects experienced an adverse reaction that required withdrawal from the study. No adverse reactions attributable to the study drugs were observed. CONCLUSION: Olmesartan is a promising ARB for BP control in hypertensive type 2 diabetics.

RESUMEN

Angiotensin II receptor blockers (ARB) are often co-administered with a calcium channel blocker (CCB) for treating hypertension. In this open-label randomised study, untreated diabetic hypertensive patients were randomised to receive either olmesartan 20 mg/day or candesartan 8 mg/day for 12 weeks. Patients with blood pressure exceeding 130/80 mm Hg received add-on 16 mg/day azelnidipine to ongoing olmesartan (OL group) or 5 mg/day amlodipine to ongoing candesartan (CA group) for 24 weeks. Home-measured and clinic-measured blood pressure decreased in both groups. Fasting blood glucose, haemoglobin A1c (HbA1c) and urinary albumin levels decreased significantly in the OL group but not in the CA group. In conclusion, this study revealed clinically relevant differences between two combinations of an ARB+CCB in diabetic hypertensive patients. Olmesartan and azelnidipine had a more persistent early morning antihypertensive effect and produced greater decreases in heart rate, fasting blood glucose and HbA1c (National Glycohemoglobin Standardization Program values) levels, and microalbuminuria than did candesartan and amlodipine.

RESUMEN

Although patients with type 2 diabetes demonstrate cardiac diastolic dysfunction, it is well known that cardiac diastolic dysfunction is produced by hypertension and aging. The purpose of the present study was to elucidate the cardiac structure and function in normotensive patients with type 2 diabetes in various age strata in order to assess the effect of diabetes mellitus itself on cardiac function. Echocardiographic examination was performed in 77 normotensive patients with type 2 diabetes (age: 63+/-11 years) and 76 healthy control subjects (age: 60+/-11 years) who were in their forties, fifties, sixties, and seventies. The left ventricular (LV) wall thickness and dimension were measured by M-mode echocardiography. The relative wall thickness, LV mass index, and LV ejection fraction (LVEF) were calculated. LV diastolic function was assessed by the peak velocity of early rapid filling (E velocity) and the peak velocity of atrial filling (A velocity), and the ratio of E to A (E/A) using the transmitral flow velocity, which were obtained by Doppler echocardiography. No difference was observed in the relative wall thickness, LV mass index, or LVEF between the diabetic patients and control subjects in any of the age strata. The E/A ratio in the patients with type 2 diabetes was not different from that in the control subjects in their 40s (1.17+/-0.35 versus 1.20+/-0.36). However, E/A was significantly lower in the diabetic patients than in the control subjects in their 50s (0.87+/-0.28 versus 1.14+/-0.24), 60s (0.78+/-0.22 versus 0.97+/-0.27), and 70s (0.66+/-0.19 versus 0.84+/-0.21) (p<0.05). The duration of type 2 diabetes was significantly longer in patients in their 50s (7.0+/-2.5 years), 60s (8.0+/-3.2 years), and 70s (10.4+/-3.2 years) than in patients in their 40s (3.3+/-1.9 years) (p<0.001). The value of E/A in the diabetic patients correlated with the duration of type 2 diabetes (r=-0.62, p<0.001). These results indicate that cardiac diastolic dysfunction without LV systolic dysfunction in patients with well-controlled type 2 diabetes is related neither to hypertension nor LV hypertrophy, but rather to aging and the duration of type 2 diabetes.

RESUMEN

The purpose of the present study was to elucidate the cardiac structure and function in patients who have metabolic syndrome but no history of cardiovascular disease by analyzing echocardiographic findings. Echocardiographic examination was performed to screen for cardiovascular disease in 135 patients who were in their sixties. Patients were divided into metabolic syndrome (n=65, age: 65+/-2.7 years) and non-metabolic syndrome (n=70, age: 66+/-2.5 years) groups based on the criteria for metabolic syndrome proposed by the Japanese Society of Hypertension and seven other societies in 2005. The left ventricular (LV) wall thickness and dimension were measured by M-mode echocardiography. The relative wall thickness, LV mass index, and LV ejection fraction (LVEF) were calculated. LV diastolic function was assessed by the peak velocity of early rapid filling (E velocity) and the peak velocity of atrial filling (A velocity), and the ratio of E to A (E/A) was assessed by the transmitral flow. The Tei index, which reflects both LV diastolic and systolic function, was also calculated. There were no differences in relative wall thickness, LV mass index, or LVEF between the two groups. However, both the EIA and Tei index were significantly different between the metabolic syndrome (0.66+/-0.14 and 0.36+/-0.07, respectively) and non-metabolic syndrome (0.88+/-0.25 and 0.29+/-0.09) groups (p<0.001). These results indicate that patients with metabolic syndrome can have cardiac diastolic dysfunction even if they have neither LV hypertrophy nor systolic dysfunction.

RESUMEN

The purpose of the present study was to analyze the relationships between echocardiographic findings, brachial-ankle pulse wave velocity, and carotid atherosclerosis in type 2 diabetic patients. In 70 type 2 diabetic patients without cardiovascular disease, pulse wave velocity was measured using an automatic waveform analyzer, and the carotid plaque score was obtained by carotid ultrasonography. The left ventricular wall thickness and the indexes of left ventricular diastolic function (the peak velocity of early rapid filling [E velocity], the peak velocity of atrial filling [A velocity], and the E/A ratio) were obtained by echocardiography. Brachial-ankle pulse wave velocity correlated significantly with the carotid plaque score, but the correlation was weak (r=0.37, p=0.001). The brachial-ankle pulse wave velocity demonstrated a strong correlation with the A velocity (r=0.73, p<0.001), the ratio of E to A (E/A) (r=-0.63, p<0.001), and the deceleration time of the E velocity (r=0.48, p<0.001). Stepwise regression analysis showed that the A velocity (beta coefficient=0.42, p<0.001) and ventricular septal thickness at the left ventricular outflow tract (beta coefficient=0.27, p=0.001) were independently associated with brachial-ankle pulse wave velocity. Stepwise regression analysis indicated that ventricular septal thickness at the left ventricular outflow tract (beta coefficient=0.38, p=0.001) was independently associated with the plaque score. These results indicate that left ventricular diastolic dysfunction as revealed by increased peak velocity of atrial filling reflects arterial stiffening in type 2 diabetic patients. In addition, myocardial wall thickening at the left ventricular outflow tract reflects not only arterial stiffening but also carotid atherosclerosis. Therefore, these abnormal echocardiographic findings of left ventricular diastolic dysfunction and myocardial wall thickening may be useful markers of the presence of progressive arteriosclerosis in type 2 diabetic patients.
