Abstract

Exercise stress testing (EST) is a sensitive and informative examination of the cardiovascular response to exercise. Exercise is a common physiological stress used to elicit cardiovascular abnormalities not present at rest and to determine the adequacy of cardiac function. The electrocardiogram is the most common parameter used to evaluate the ischemic response during exercise. Exercise electrocardiography is one of the most frequent noninvasive modalities used to determine the likelihood and extent of coronary artery disease. The test is also used to estimate prognosis, to determine functional capacity, and to evaluate the effects of therapy. The indications, contraindications, protocol, when to terminate, interpretation of the result, and spesific clinical applications will be reviewed in this paper.

Abstract

Atherosclerosis causes significant morbidity and mortality. Carotid intima-media thickness (CIMT) can predict the onset of cardiovascular and ischemic stroke in the future. CIMT, the measurement of atherosclerosis, is determined in vivo using carotid ultrasound. CIMT is associated with traditional cardiovascular risk factors such as age, sex, race, smoking habits, alcohol consumption, exercise habits, blood pressure, dyslipidemia, dietary patterns, medications used, glycemia, hyperuricemia, anthropometric parameters associated with obesity. In addition, CIMT is also associated with novel risk factors, ie genotypes, cardiovascular anthropometry parameters, rheumatoid arthritis, immunologic diseases, inflammatory cytokines, lipid peroxidation, chemocyte anthropometric parameters, infectious diseases, vitamin D, matrix metalloproteinases, and other diseases

Abstract

The Covid-19 pandemic has caused significant global mortality and morbidity. Covid -19 infection is caused by the SARS-CoV-2 virus, which requires a receptor on the host cell to enter, primarily Angiotensin-Converting Enzyme 2, encoded by the ACE2 gene, and Transmembrane Serine Protease 2, encoded by the TMPRSS2 gene. Several factors can influence Covid-19 mortality and morbidity, including gender, comorbidities such as diabetes mellitus (DM), obesity, cardiovascular diseases, and genetic factors. ACE2 and TMPRSS2 polymorphisms are believed to worsen the condition of Covid-19 patients. This study aimed to identify polymorphisms in the ACE2 (rs2285666 G>C) and TMPRSS2 (rs2070788 A>G) in  Covid-19 survivors with hypertension and diabetes mellitus. The total sample was 30 hypertension and diabetes mellitus   patients treated at Islamic Hospital Surabaya. A total of 3 ml of blood was drawn from the median cubital vein and placed into an EDTA vacutainer. DNA extraction was performed using the High Pure PCR Template Preparation Kit (Roche). Identification of ACE2 and TMPRSS2 polymorphisms was performed using the rhAmp SNP genotyping method with the LightCycler® system (Roche 480II). Genotyping results for ACE2 showed that 55.2% of patients had the GG (wild-type) with a G allele frequency of 68.9%. Genotyping for the TMPRSS2 showed that 60% of patients had the GG (mutant-type) with a G allele frequency of 78.3%. During Covid-19 infection, neither GG genotype (ACE2) and the GG genotype (TMPRSS2) exhibited severe symptoms.
