Carotid Plaque Burden in Patient who Underwent Coronary Angiogram at Dhulikhel Hospital.

Background Coronary artery disease (CAD) is a leading cause of death worldwide and is primarily caused by atherosclerosis. Carotid plaque and coronary artery disease share a common pathogenesis and risk factor. Carotid arteries are accessible through noninvasive 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.

Prevalence of Microalbuminuria in Patients of Essential Hypertension and its Correlation with Left Ventricular Hypertrophy and Carotid Artery Intima­media Thickness.

Background Urinary albumin excretion has been associated to cardiovascular events and increased mortality in hypertensive patients. 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.

Angiographic Severity of Coronary Artery Disease in Diabetic and Non-diabetic Acute STEMI Patients in a Tertiary Care Centre of Nepal.

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 nondiabetics 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.

Lyme disease overdiagnosis in a large healthcare system: a population-based, retrospective study.

OBJECTIVES: To evaluate the impact of false-positive IgM immunoblots on Lyme disease treatment and case reporting in a large healthcare system. METHODS: We obtained the results of all Lyme disease serological tests ordered at U.S. Air Force healthcare facilities in the USA between January 2013 and December 2017. We conducted chart reviews to adjudicate positive IgM immunoblots (from two-tier and independent testing) as true positives or false positives using established criteria, and we assessed whether these cases were reported to the U.S. Department of Defense surveillance system. RESULTS: Of the 18 410 serum tests (17 058 immunoassays and 1352 immunoblots) performed on 15 928 unique individuals, 249/1352 (18.4%) IgM immunoblots were positive. After excluding repeat tests, insufficiently documented cases, and participants with a history of Lyme disease, 212 positive IgM immunoblot cases were assessed. A total of 113/212 (53.3%) were determined to be false positives. Antibiotics were prescribed for Lyme disease for 97/99 (98.0%) participants with a true-positive test and 91/113 (80.5%) participants with a false-positive test. The number of false-positive cases reported to the surveillance system was identical to the number of unreported true-positive cases (n = 44). CONCLUSIONS: Lyme disease serological tests were overused in a large healthcare system, and positive results were frequently misinterpreted, leading to misdiagnosis and widespread antibiotic misuse. Underreporting of true-positive cases was offset by overreporting of false-positive cases, suggesting that the discrepancy between the reported incidence and true incidence of Lyme disease may not be as significant as previously assumed.

Need for improvement of medical records.

INTRODUCTION: A medical record is a systematic documentation of a patient's medical history and care for legal and future use. A poor quality medical record can negatively affect patient care and safety. The study aims to assess the adequacy of medical records in Bir Hospital, a central hospital. METHODS: A cross-sectional study was conducted by analyzing consecutive discharge summaries of patients admitted during a 6 month period in a single unit of a tertiary care center. The discharge summary format of the hospital was taken as the standard and evaluation for adequacy of data entered was assessed. Descriptive statistics were used to analyze various statistical discrepancies. RESULTS: Patient's condition at discharge was missing in 86 (66.15%). Patient's address was missing in 21 (16.1%) cases. Almost all the discharge sheets lacked mailing address. Total 96 (73.8%) had use of abbreviations diagnosis. Age and sex were missing in 1 (0.76%). Doctor's signature was illegible in 103 (79.3%) and missing in 2 (1.5%) summaries. Doctor's name and their level/position were missing in 118 (90.76%) and 125 (96.1%) respectively. Total 126 patients (96.9%) were not given any instructions on discharge. CONCLUSIONS: The discharge summaries analyzed were seen to be inadequate especially in documenting course during the hospital stay, condition at discharge, appropriate instructions and the treating physician's details. These can probably be addressed by introducing electronic medical records if feasible. Otherwise, the discharge summary should be standardized and doctors should be trained to write legible, complete discharge summaries.

Novel substituted naphthalen-1-yl-methanone derivatives as anti-hyperglycemic agents.

A series of aminoalkoxy phenyl-substituted naphthalene-1-yl-methanone was synthesized and tested for its anti-hyperglycemic activity in SLM and STZ-S rat models. Some compounds (3b, 4c and 4h) of the series were showing significant anti-hyperglycemic activity in male Sprague-Dawley rats in sucrose-loaded model (SLM) as well as in streptozotocin-induced model (STZ-S). Active compounds were also evaluated for relative binding affinity against glucagon receptor.

Individuals at Risk of Coronary Heart Disease (CHD), its Prevention and Management by an Indigenous Compound.

A variety of rist factors have been suspected for causing the coronary heart disease. 406 cases of both sex groups with age range of 35 to 55 years were selected from three distinct localities of varanasi city. Individuals who reported single or more risk factors of CHD were isolated from the population of the particular areas. After a detailed preliminary screening of the subjects various physical, physiological, psychological and biochemical measurements were carried out. Other basis of initial findings, the cases who sowed abnormal lipid profile with dominant psychological involvement were given the organic extract of Inula racemosa (Pushkarmool), commiphora mukul (Guggulu), centella asiatica (Mandukaparni) and Hypericum perforatum (Basant in prescribed doses continuously for 6 moths. Correction in the lipid profile including triglycerides, blood pressure and the psychological factors like anxiety and depression to a significant level following least drugs treatment indicated the cardioprotective and therapeutic effects of the present formulation.Hence, by modifying the coronary risk factors, the incidence of CD can be minimized to a great extent as well as the test formulation may also be advocated in the prevention and management of CHD.
