          Influence of heart rate on mortality among persons with hypertension: the Framingham Study.

          Previous studies have shown positive associations between heart rate and both all-cause and cardiovascular mortality. These relationships, however, have not been investigated in persons with hypertension. Using 36-year follow-up data from the Framingham Study, we evaluated from 4530 subjects, aged 35 to 74, whose blood pressures were > or = 140 mm Hg systolic or > or = 90 mm Hg diastolic and who were not treated with antihypertensive medication. We used pooled logistic regression to calculate biennial mortality rates. Odds ratios and 95% confidence intervals for each increment in heart rate of 40 beats/min, adjusted for age and systolic blood pressure level, were: for all-cause mortality, 2.18 (1.68, 2.83) for men and 2.14 (1.59, 2.88) for women; and for cardiovascular mortality, 1.68 (1.19, 2.37) for men and 1.70 (1.08, 2.67) for women. Exclusion of outcomes in the first 2 or 4 years after measurement of heart rate did not materially change the results, which suggests that rapid heart is not merely an indicator of preexisting illness. Therefore heart rate may be an independent risk factor for cardiovascular death in persons with hypertension.

            Mean Platelet Volume in Type 2 Diabetes Mellitus

            Context: diabetes mellitus is a global pandemic. The increased platelet activity may play a role in the development of vascular complications of this metabolic disorder. The mean platelet volume (MPV) is an indicator of the average size and activity of platelets. Larger platelets are younger and exhibit more activity. Aims: to determine the MPV in diabetics compared to nondiabetics, to see if there is a difference in MPV between diabetics with and without vascular complications, and to determine the correlation of MPV with fasting blood glucose, glycosylated hemoglobin (HbA1c), body-mass index, and duration of diabetes in the diabetic patients. Materials and Methods: platelet counts and MPV were measured in 300 Type 2 diabetic patients and 300 nondiabetic subjects using an automated blood cell counter. The blood glucose levels and HbA1c levels were also measured. Statistical evaluation was performed by SPSS using Student's t test and Pearson correlation tests. Results: the mean platelet counts and MPV were higher in diabetics compared to the nondiabetic subjects [277.46 ± 81 X 109/l vs. 269.79 ± 78 X 109/l (P= 0.256)], 8.29 ± 0.74 fl versus 7.47 ± 0.73 fl (P= 0.001), respectively. MPV showed a strong positive correlation with fasting blood glucose, postprandial glucose and HbA1C levels (P=0.001). Conclusions: our results showed significantly higher MPV in diabetic patients than in the nondiabetic subjects. This indicates that elevated MPV could be either the cause for or due to the effect of the vascular complications. Hence, platelets may play a role and MPV can be used as a simple parameter to assess the vascular events in diabetes.

              Cardiac autonomic neuropathy predicts renal function decline in patients with type 2 diabetes: a cohort study.

              The aim of this work was to assess the impact of cardiac autonomic neuropathy (CAN) on the development and progression of chronic kidney disease (CKD) in patients with type 2 diabetes.
