Publication Angiographic Severity of Coronary Artery Disease in Diabetic and Non-diabetic Acute STEMI Patients in a Tertiary Care Centre of Nepal(Kathmandu University, 2021) Pathak, SR; Gajurel, RM; Poudel, CM; Shrestha, H; Thapa, S; Thapa, S; Koirala, PABSTRACT Background Patients with diabetes mellitus have a higher prevalence of atherosclerotic heart disease and a higher incidence of myocardial infarction than the general population. Definitive diagnosis and precise assessment of anatomic severity of Coronary Artery Disease requires invasive diagnostic modality like coronary angiography. Objective To study angiographic characteristics and severity involving coronary arteries in patients with acute ST segment elevation Myocardial infarction and to compare the same in diabetics and non-diabetics. Method Among 150 patients with acute coronary syndrome, 75 diabetics and 75 non- diabetics admitted in Manmohan Cardiothoracic vascular and transplant Centre were selected randomly during a period of one year formed the study group. Random Blood Sugar, Fasting Blood Sugar was done in all 150 patients, HbA1c in all diabetics. All subjects with acute ST Elevation Myocardial Infarction were taken up for coronary angiography intended for primary PCI. Result In our study, 35 (46.7%) out of 75 diabetic patients had triple or multi-vessel disease compared to 10 (13.4%) out of 75 non diabetics. Non-diabetic patients had significantly higher single vessel disease (65.3%). There was a statistically significant association of duration of DM with vessels involved. The occurrence of Triple Vessel Disease/Multivessel Disease was significantly higher in the patients with DM duration > 10 years compared to patients with DM duration < 10 years (64.7% vs. 35.3%, P < 0.001), however there was no significant difference in type of vessel involved. Similarly, a significantly higher proportion of Triple vessel disease was observed in patients with poor glycemic control (HbA1c > 8.5%). 72.2% of the patients with HbA1c > 8.5% had Triple vessel disease/Multi vessel disease, whereas patients with good glycemic control (HbA1c < 7.0%) had predominantly Single vessel disease (90.0%), with no occurrence of Triple vessel disease/Multi vessel disease Conclusion Diabetic patients presenting with ST Elevation Myocardial Infarction are likely to have triple/multiple vessel disease compared to non-diabetic patients. The occurrence of Triple Vessel Disease/Multivessel Disease was significantly higher in the patients with DM duration > 10 years compared to patients with DM duration <10 years.

Carotid plaque and coronary artery disease share a common pathogenesis and risk factor. Carotid arteries are accessible through non- invasive imaging method. By characterizing the carotid arteries, it becomes possible to estimate the total burden of atherosclerosis, including that of coronary artery disease. According European Society of Cardiology (ESC) ultrasound of the carotid arteries should be considered, and be performed to detect plaque in patients with suspected chronic coronary syndrome. Objective To establish a relationship between coronary artery disease and carotid plaque. Method It is a cross sectional analytical study. Patients who underwent coronary angiogram at Dhulikhel Hospital from 1st April 2022 till 31st March 2023 were assessed for carotid plaque using carotid ultrasound. Chi square test was done to find the relationship between presence of carotid plaque and coronary artery stenosis of more than 50%. Positive predictive value and negative predictive value was calculated. Result Total number patient was 254 and the mean age was 61± 4.7 years. Out of which 85(33.5) had normal coronary artery, 143(56.3) had ≥ 50% stenosis and 120 (47.2) had ≥ 70% stenosis. Eight patients also had significant left main disease with ≥ 50 % stenosis. Carotid plaque was present in 121(47.6) patients. Out of 143 patients who had ≥ 50% stenosis in coronary angiogram, 104(72.7) patients also had carotid plaque which is statistically significant as p < 0.05. Positive predictive value (PPV) was 72.7% and negative predictive value was 84.7%. Conclusion This study establishes a relationship between coronary artery disease and carotid plaque, suggesting that the presence of carotid plaque may serve as an indicator of underlying coronary artery disease.

There is limited information among Nepalese patients about the implications of microalbuminuria (MA) in the setting of hypertension and potential cardiovascular morbidity. Objective To investigate the prevalence of microalbuminuria in patients with essential hypertension and its connection with left ventricular hypertrophy (LVH) and carotid artery intima-media thickness (cIMT). Method The study involved 80 hypertension individuals in total. All patients in the study had basic biochemical tests, routine urine evaluations, echocardiography, and carotid artery intima-media thickness measurements performed, and the data were analyzed. Result The prevalence of microalbuminuria was present in 37.5% cases of essential hypertension. The mean left ventricular mass index (LVMI) was significantly higher in patients with increased microalbuminuria as compared to patient with normal microalbuminuria. In addition, a significant positive correlation between microalbuminuria and left ventricular hypertrophy was also observed. Furthermore, mean carotid artery intima-media thickness was found to be higher in patients with microalbuminuria (p < 0.001), with 76.7% of the patients with microalbuminuria having elevated mean carotid artery intima-media thickness. The carotid artery intima-media thickness had a positive correlation with both microalbuminuria and left ventricular hypertrophy. Conclusion Microalbuminuria assessment in hypertensive patients is an important test for the evaluation of target organ damage. This study shows that microalbuminuria is common in hypertension patients, particularly those with left ventricular hypertrophy. Microalbuminuria was found to be associated with left ventricular hypertrophy and carotid artery intima-media thickness.
