Background: Type 2 diabetes mellitus (T2DM) patients have a higher risk of developing micro- and macrovascular complications, which lead to decrease in the quality of life and increase in morbidity. Platelet indices have been available in the laboratory routine using blood cell counters for several years. These indices could alert us regarding endothelial dysfunction and in turn regarding the microvascular complications. Hence, this study was done to prove the correlation between platelet indices and microvascular complications in T2DM. Materials and Methods: In total, 125 diabetic patients attending diabetes OPD and admitted in medicine department along with age and sex-matched non-diabetic controls were studied. A detailed history was taken regarding duration of diabetes, medication, past history of stroke, IHD, and hypertension. Patients with T2DM were specially evaluated for microvascular complications. Platelet indices, fasting blood glucose, Post prandial blood glucose, HbA1C, and Sr. Creatinine were obtained from venous blood samples. All parameters were then subjected to statistical analysis using SPSS 17.0. Results: Platelet indices, namely MPV, PCT, PDW, and P/LCR were significantly higher in diabetic individuals than those in age and gender-matched controls. Moreover, the increase in MPV, PDW, and P/LCR was more significant in diabetic subjects with microvascular complications when compared with those without microvascular complications. Platelet dysfunction also showed a positive association with HbA1C, retinopathy, nephropathy, and neuropathy individually. Conclusions: Changes in platelet indices were found to be statistically associated with diabetes and its complications.
A winking coronary sign refers to the partial collapse of an artery situated over the ventricular septal rupture during systole and refilling of the same during diastole, which is seen as phasic filling and disappearance of the arterial segment during coronary angiography. In this article, we discuss the case of a patient who reported to the emergency department of a tertiary care hospital in central India with myocardial infarction of the anterior wall. Two-dimensional echocardiography and coronary angiography revealed ventricular septal rupture. The patient was promptly managed by a percutaneous coronary angiography and interventricular septal device closure. Even after the defect closure, the winking coronary sign persisted on coronary angiography, and the patient was then discharged in stable condition.
Peripheral vascular disease in association with renal artery stenosis is an important association which predicts the severity of the disease. An increase in the number of vessels affected by peripheral vascular disease increases the chances of renal artery stenosis. In our case, the patient had primarily presented with anginal chest pain with complaints of claudication which on further investigation was diagnosed to be a triple vessel coronary artery disease along with bilateral subclavian and bilateral renal stenosis. On detailed history taking, risk factors like hypertension and chronic smoking was found to be present in our case which predisposed to peripheral artery disease secondary to atherosclerosis which was diagnosed on further investigations. Although the association of renal artery stenosis is not very rare in cases of severe peripheral vascular diseases, the presence of a triple vessel coronary artery disease in synchrony is what makes it unique. Take away lesson from this case report is importance of early diagnosis of dyslipidemia causing atherosclerosis and its complications. Multiple atherosclerotic lesions in synchrony i.e, bilateral renal artery stenosis with bilateral subclavian artery stenosis with coronary artery triple vessel atherosclerotic disease like in our case and its severity should create awareness among health care individuals and early treatment measures including lifestyle modifications should be considered to avoid such drastic events.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
