Exercise Improves Survival Rates for Diabetics with LVH
- Categorized in: Department of Defense (DoD), Department of Veterans Affairs (VA), Diabetes, September 2012
Achieving a certain level of physical fitness can improve survival rates of patients with diabetes who also have left ventricle hypertrophy (LVH), according to a new study.1
The research, presented at The Endocrine Society's 94th Annual Meeting in Houston this past summer, found that diabetic patients who were not physically fit and had LVH were the most likely to die, with physically-fit patients — regardless of whether they had LVH — having a significantly lower risk of death. Those differences remained even after investigators adjusted for high blood pressure, excess body weight, smoking and medication usage.
Compared to patients with low physical-fitness levels and no LVH, patients who were not physically fit and had LVH were at a 20% greater chance of dying. When patients were physically fit, however, those without LVH had a 41% reduced chance of dying, and those with LVH showed a 43% reduction, compared with the control group.
"Exercise fitness markedly improves survival in patients with type 2 diabetes and left ventricle hypertrophy," said lead author Khaled A. Alswat, MBBS, endocrinology fellow at the Washington, DC, VAMC and George Washington University. "We also found that improvement in fitness improves survival significantly, regardless of the presence or absence of left ventricle wall thickness."
The study looked at 866 male veterans with type 2 diabetes and an average age of 61 from 1986 to 2011 at the Washington, DC, VAMC.
When the study began, participants underwent a standard exercise assessment with a treadmill to determine fitness level and were then classified as either low fit or physically fit. In addition, all patients received an echocardiogram to diagnose LVH. Over the follow-up period, which was as long as 24 years with a median of nearly nine years, 346 deaths occurred at an annual rate of 4.3%.

Diabetes Patients Quit Smoking at Higher Rates after Hospitalization
Patients with diabetes have a higher likelihood of successfully quitting smoking after hospitalization than some other groups, according to a new study that recommends more intensive tobacco cessation programs for this population.
The study, which looked at 496 patients who had acute-care hospitalization in three Midwestern VAMCs in VISN 11, looked at six-month post-hospitalization tobacco cessation rates among veterans with and without diabetes.1
For the research, patients with a mean age of 55.2 years, 62% white, were asked to complete a follow-up survey six months post-discharge. Of the study group, 29% had comorbid diabetes.
Bivariate- and multivariable-adjusted analyses were then conducted to determine differences in tobacco cessation rates between patients with and without a diagnosis of diabetes.
Researchers found that 18.8% of patients with diabetes reported tobacco cessation at six months, compared with 10.9% of those without diabetes (P = 0.02). Cotinine-verified cessation rates were 12.5 vs. 7.4% in the groups with and without diabetes, respectively (P = 0.07).
Controlling for psychiatric co-morbidities, depressive symptoms, age, self-rated health and nicotine dependence, the multivariable-adjusted logistic regression showed that patients with diabetes had three times higher odds of six-month cotinine-verified tobacco cessation as compared with those without diabetes (odds ratio 3.17, P = 0.005).
The study, conducted by the VA Center for Clinical Management Research at the VA Ann Arbor Healthcare System as well as the University of Michigan School of Nursing in Ann Arbor, was published this summer in the journal Diabetes Medicine.
