Common Causes Of Death In The Patients Suffering From Both Type 2 Diabetes And Atherosclerotic Cardiovascular Diseases (ASCVD)
An earlier study shows that the heart attack (acute myocardial infarction is the medical name. MI) is causing the maximum number of deaths and type 2 diabetes (T2D) may be linked with other causes of death such as cancer, heart failure, sudden death and noncardiovascular deaths.
A three-year, double-blind and Placebo-controlled study called TECOS (Trial Evaluating Cardiovascular Outcomes with Sitagliptin) has studied the causes, risk factors and prevention of mortality (death) in patients suffering from both atherosclerotic cardiovascular disease (ASCVD) and type 2 diabetes.
Researchers have evaluated the effects of Sitagliptin (DPP-4 Inhibitor) drug along with their current drug therapy on patients suffering from both atherosclerotic cardiovascular disease (ASCVD) and type 2 diabetes. The total number of the participants in the study are 14,735, aged more than 50 years. All of them are diagnosed with both type 2 diabetes and atherosclerotic cardiovascular diseases (ASCVD). They are selected randomly into the study groups of either Placebo or Sitagliptin. Researchers used the Cox proportional hazard model to determine the risk factor associated with the cause of death.
During a three-year follow-up study, the researchers have observed the following deaths due to various causes.
The malignancy was seen in 46 percent of deaths (145) in the deaths due to a non-cardiovascular disease.
The following table shows the causes and number of deaths due to cardiovascular diseases.
The study shows a decrease in cardiovascular death (mortality) such as sudden death, stroke and heart failure in the patients without a heart failure history. Cardiovascular mortality can be lowered with measures such as the prevention of heart failure, lowering blood sugar (glucose) levels (HbA1c) and eGFR preservation.
The study also found a lower risk of all-cause mortality in women with a high estimated glomerular filtration (eGFR) and having a history of percutaneous coronary intervention (coronary angioplasty. PCI).
This study shows the "Sudden Death" is the most frequent cause of death in the deaths related to cardiovascular diseases in patients of both type 2 diabetes and atherosclerotic cardiovascular diseases (ASCVD). But the reasons for the "Sudden Death" are not known. Researchers say that further investigation is required to uncover the mechanism.
Limitations of this study are:
