A Study of Electrocardiographic Changes in patients with Newly Diagnosed Primary Hypothyroidism: A Cross-Sectional Study

Background: The thyroid hormones have an important role in the cardiovascular system; even minimal change in its level can cause significant alteration in the cardiac activity which can cause considerable electrocardiographic changes. We conducted this study to assess the electrocardiographic (ECG) changes in patients who were newly diagnosed with primary hypothyroidism. Methods: This study is a descriptive cross-sectional study conducted among 71 newly diagnosed subclinical and overt primary hypothyroidism patients visiting the out-patient department (OPD) of Universal College of Medical Sciences, Nepal from December 2018 to June 2020 after taking ethical clearance from the institutional review committee (UCMS/IRC/212/18). ECG was obtained for each patient at the time of diagnosis of primary hypothyroidism. The data were analyzed with SPSS Version 16. Results: The most common ECG changes were sinus bradycardia seen in 32.4%, followed by T wave inversion in 21.1%, low voltage QRS complex in 15.5%, and prolonged PR interval in 14.1%. ECG changes were seen in 62% of cases of newly diagnosed primary hypothyroidism. Among all patients, subclinical hypothyroidism accounted for 7%, while overt hypothyroidism accounted for 55% of the ECG findings. Conclusion: Our study found ECG changes like sinus bradycardia, T wave inversion, low QRS voltage, and prolonged PR interval in newly diagnosed primary hypothyroidism. We suggest that every newly diagnosed hypothyroid patient should be evaluated for ECG changes

Study of Serum Uric Acid Level in Acute Coronary Syndrome in Nepalese Subjects

At present, cardiovascular diseases are global health problems responsible for 17.3 million deaths per year and adding extra burden in developing countries like Nepal. Studies show that serum uric acid (SUA) can result in endothelial dysfunction which can lead to vascular disease like stroke. In this study, we determined serum uric acid levels in patients with acute coronary syndrome (ACS) and assess its risk factors. A cross sectional study was conducted in 82 patients with ACS who fulfilled the inclusion criteria included in the study and their serum uric acid level were investigated. It was found that 51 (62.2%) were males and 31 (37.8%) were females. Mean age in study population was 60.26 ± 11.34 years. Majority of the population belongs to 56-65 years age group. The mean uric acid level of our study population was 6.03 ± 1.50 mg/dl (male = 5.92 ± 1.72, female = 6.64 ± 1.53). SUA ? 7 mg/dl was maximum in 56-65 years age group and there was no association between age and SUA (P value = 0.146). Over half of the study population were hypertensive i.e. 42 (51.21%) and smoker i.e. 43 (52.43%). It showed association between SUA and ACS (P value = 0.003). Among those having diabetes, maximum have SUA ? 7 mg/dl i.e. 17 (47.22%). Among those having high cholesterol level, male have higher incidence than female with no association between T. Cholesterol and gender (P value = 0.49). The mean value of T. Cholesterol was 189.83 ± 46.81 mg/dl (male = 198.78 ± 55.19 mg/dl, female = 202.30 ± 54.92 mg/dl) with (P value = 0.52). In conclusion, the mean age of ACS patients was 60.26 years, with the peak incidence at the age of 56-65 years. The ACS had male predominance. The potential risk factors of ACS were: Age >56 years (65.83%), male sex (62.2%), dyslipidemia (35.36%, hypertension (51.2%), diabetes mellitus (43.9%), smoking (52.4%) and alcohol consumption (39%). Among these SUA significantly associated with risk factors were- Sex, Diabetes Mellitus, T. Cholesterol. There was association between serum uric acid level and ACS patients. Hypertension and smoking constitutes one of the major risk factor for ACS in study population

Strenuous Exercise-Induced Tremendously Elevated Transaminases Levels in a Healthy Adult: A Diagnostic Dilemma

The liver function test (LFT) is a commonly performed test in clinical practice in order to assess well-being of the liver; however, derangement in liver enzymes, however, may not necessarily imply an underlying liver pathology. The standard liver function test measures alanine aminotransferase (ALT), aspartate aminotransferase (AST), alanine phosphatase (ALP), bilirubin levels (total, direct, and indirect), proteins (total protein and albumin), and PT-INR (prothrombin time and international normalized ratio). In addition to common causes, liver enzyme levels can also be elevated due to extrahepatic causes, such as muscular injury can elevate transaminases levels. Here in, we present a case of an asymptomatic healthy male who was doing vigorous exercise and presented with reports of elevated transaminase levels. During evaluation of the case, most of his reports came to be within normal range. Additionally, when reevaluated after discontinuation of vigorous exercise, 3 weeks later and then a month later, his liver enzyme levels were observed to be within normal range. Hence, we suspect that muscle damage-induced transaminitis might not have been considered in the differential diagnosis during the evaluation of a patient with raised transaminases levels and also suggest that it should be kept as a differential in the given scenario
