RESUMEN
OBJECTIVES: Describe the incidence of cardiac complications in patients admitted to hospital with COVID-19 in Australia. DESIGN: Observational cohort study. SETTING: Twenty-one (21) Australian hospitals. PARTICIPANTS: Consecutive patients aged ≥18 years admitted to hospital with laboratory confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. MAIN OUTCOME MEASURES: Incidence of cardiac complications. RESULTS: Six-hundred-and-forty-four (644) hospitalised patients (62.5±20.1 yo, 51.1% male) with COVID-19 were enrolled in the study. Overall in-hospital mortality was 14.3%. Twenty (20) (3.6%) patients developed new atrial fibrillation or flutter during admission and 9 (1.6%) patients were diagnosed with new heart failure or cardiomyopathy. Three (3) (0.5%) patients developed high grade atrioventricular (AV) block. Two (2) (0.3%) patients were clinically diagnosed with pericarditis or myopericarditis. Among the 295 (45.8%) patients with at least one troponin measurement, 99 (33.6%) had a peak troponin above the upper limit of normal (ULN). In-hospital mortality was higher in patients with raised troponin (32.3% vs 6.1%, p<0.001). New onset atrial fibrillation or flutter (6.4% vs 1.0%, p=0.001) and troponin elevation above the ULN (50.3% vs 16.4%, p<0.001) were more common in patients 65 years and older. There was no significant difference in the rate of cardiac complications between males and females. CONCLUSIONS: Among patients with COVID-19 requiring hospitalisation in Australia, troponin elevation was common but clinical cardiac sequelae were uncommon. The incidence of atrial arrhythmias and troponin elevation was greatest in patients 65 years and older.

A hyperdominant left anterior descending coronary artery variation is a rare but important diagnosis because of the risk for large-territory ischemia. We describe a very rare presentation of spontaneous coronary artery dissection in the distal portion of a hyperdominant left anterior descending coronary artery. No similar cases have been described.
RESUMEN
BACKGROUND: In the current two decades, dyslipidemia and increased blood glucose as metabolic abnormalities are the most common health threats with a high incidence among HIV/AIDS patients on antiretroviral (ARV) treatment. Scientific investigations and reports on lipid and glucose disorders among HIV infected communities are inadequate especially in those developing such as Malaysia. This cross-sectional survey was mainly aimed to evaluate the prevalence of metabolic abnormalities and associated risk factors among HIV infected population patients on ARV medication. METHODS: In a single reference health center in Malaysia, 2739 adult HIV positive patients on antiretroviral therapy (ART) were studied cross-sectionally using medical records. Besides demographic variables and associated health disorders, those factors which can change the lipid and glucose levels were collected. Logistic Regression was used to find the potential risk factors (p < 0.05). RESULTS: Majority of the studied population were male (81.1%) and aged between 30-49 (68.6%). Mean CD4 count was 474.25 (cells/mm3) while undetectable RNA viral load was common among 83.3 (%) of subjects. Among 1,583 patients with the recent blood lipid and glucose tests, increased levels of triglyceride (TG) and total cholesterol (TC) were frequently prevalent in half of the population as 59 (%) and 54.2 (%) while 28.7 (%), 35.1 (%) and 38.2 (%) had declined level of high-density lipoprotein (HDL), raised low-density lipoprotein (LDL) and fasting plasma glucose (FPG) which were less common. Dyslipidemia was common in 82.3 (%) of the subjects. Notably, medication with protease inhibitor (PI) was a potential risk for elevated triglyceride (odds ratio (OR) = 2.309, 95% confidence interval (CI) = 1.605-3.324, P = 0.001), high TC (OR = 1.561, 95% CI = 1.123-2.169, P = 0.008) and low HDL (OR = 1.449, 95% CI = 1.037-2.024, P = 0.029). As lifestyle factor, alcohol consumption results as significant risk factor for raised TG (OR = 2.653, 95% CI = 1.353-5.202, P = 0.004). Also having hepatitis raised risk of high FPG level (OR = 1.630, 95% CI = 1.197-2.220, P = 0.002) in this sample population. CONCLUSIONS: Dyslipidemia is highly common in Malaysian HIV subjects receiving ARV medication. Lifestyle modification, changing PI and switch to other ARV regimen can help in reduction of these abnormalities. Also suitable strategies and plans are necessary to prevent cardiovascular diseases in future.

Chronic tricuspid regurgitation (TR) results in progressive right ventricular (RV) volume overload, followed by right-sided chamber dilatation, RV systolic dysfunction, and eventual low-output cardiac failure. Severe TR is associated with considerable morbidity and mortality, and yet until recently, patients in the late stage of their disease course had limited treatment options. Cognizant of the high mortality rates associated with surgical intervention, tricuspid valve (TV) transcatheter edge-to-edge repair (TEER) has emerged as a promising solution for patients with severe TR. As has been learned from the transcatheter mitral valve TEER experience, detailed morphological and mechanistic assessment of the TV with transthoracic and transesophageal imaging is essential to optimal patient selection and procedural success. The current review will provide a comprehensive overview of TV anatomy, the updated mechanistic classification of TR, and key echocardiographic considerations in the evaluation, management, and follow-up of patients undergoing TV TEER.

OBJECTIVE: This study aimed to explore the adverse drug reactions (ADRs) reported by patients and to identify drug-drug interactions (DDIs) among human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients. SUBJECTS AND METHODS: This cross-sectional study was conducted at the Medication Therapy Adherence Clinic, Hospital Sungai Buloh, an HIV/AIDS referral centre. The patients were randomly selected and were encouraged to describe ADRs caused specifically by any of the prescribed antiretroviral drugs (ARDs). Sociodemographic characteristics were recorded from the patients' medical records. In addition data on antiretroviral treatment (ART), DDIs and other conventional medication were also documented. RESULTS: A total of 325 randomly selected HIV/AIDS patients with a mean age of 22.94 years participated in the study. The most frequently prescribed ARDs were lamivudine (64.6%), zidovudine (40.6%) and efavirenz (42.5%). Commonly reported ADRs were fatigue (54.8%), allergic reactions (41.5%), weight loss (41.5%), dry mouth (35.1%) and memory loss (35.1%). Female (87.8%), non-complementary and alternative medicine (CAM) users (87.3%) and participants below 50 years old (81.1%) were identified as having a higher prevalence of ADRs compared to males (79.6%), CAM users (78.7%) and participants aged 50 years or more (77.5%). Patient age was found to be significantly associated (p = 0.048) with the ADRs. In addition, a total of 44 cases of DDIs belonging to category D were also found in this study. CONCLUSIONS: This study enabled us to identify the most common ADRs and DDIs associated with the use of ART. Safe and effective treatment depends on the healthcare providers' knowledge of the same.

OBJECTIVE: To assess whether hypertension is an independent risk factor for mortality among patients hospitalised with COVID-19, and to evaluate the impact of ACE inhibitor and angiotensin receptor blocker (ARB) use on mortality in patients with a background of hypertension. METHOD: This observational cohort study included all index hospitalisations with laboratory-proven COVID-19 aged ≥18 years across 21 Australian hospitals. Patients with suspected, but not laboratory-proven COVID-19, were excluded. Registry data were analysed for in-hospital mortality in patients with comorbidities including hypertension, and baseline treatment with ACE inhibitors or ARBs. RESULTS: 546 consecutive patients (62.9±19.8 years old, 51.8% male) hospitalised with COVID-19 were enrolled. In the multivariable model, significant predictors of mortality were age (adjusted OR (aOR) 1.09, 95% CI 1.07 to 1.12, p<0.001), heart failure or cardiomyopathy (aOR 2.71, 95% CI 1.13 to 6.53, p=0.026), chronic kidney disease (aOR 2.33, 95% CI 1.02 to 5.32, p=0.044) and chronic obstructive pulmonary disease (aOR 2.27, 95% CI 1.06 to 4.85, p=0.035). Hypertension was the most prevalent comorbidity (49.5%) but was not independently associated with increased mortality (aOR 0.92, 95% CI 0.48 to 1.77, p=0.81). Among patients with hypertension, ACE inhibitor (aOR 1.37, 95% CI 0.61 to 3.08, p=0.61) and ARB (aOR 0.64, 95% CI 0.27 to 1.49, p=0.30) use was not associated with mortality. CONCLUSIONS: In patients hospitalised with COVID-19, pre-existing hypertension was the most prevalent comorbidity but was not independently associated with mortality. Similarly, the baseline use of ACE inhibitors or ARBs had no independent association with in-hospital mortality.

OBJECTIVES: The primary objective of this study was to evaluate the pattern of use, reasons for use, and perceived effect of complementary and alternative medicine (CAM), accompanied by identification and comparison of the factors that are potentially associated with CAM use. DESIGN: This cross-sectional study was carried out in 325 randomly sampled patients with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), at HIV/AIDS referral clinics in the Hospital Sungai Buloh, Malaysia. Simple random sampling was used, where randomization was done using patients' medical record numbers. SUBJECTS AND METHODS: Semistructured face-to-face interviews were conducted using 38 questions pertaining to type, pattern, perceived efficacy, adverse effects, and influential factors associated with CAM use. In addition, CD4 count and viral load readings were recorded. RESULTS: Of 325 randomly sampled patients with HIV/AIDS, 254 of them were using some forms of CAM, resulting in a utilization rate of 78.2%. Vitamins and supplements (52.6%), herbal products (33.8%), and massage (16.6%) were the top three most frequently used CAM modalities. Sociodemographic factors including education level (p = 0.021, r(s) = 0.148), monthly income (p = 0.001, r(s) = 0.260), and family history of CAM use (p = 0.001, r(s) = 0.231) were significantly associated and positively correlated with CAM use. However, the majority of these patients (68%) did not disclose CAM use to health care professionals. About half of those who rated their health as good or very good perceived it as a result of CAM use. CONCLUSIONS: This study confirmed the range of 30%-100% CAM use among individuals infected with HIV/AIDS. Although, on the one hand some types of CAM reduced viral load and enhanced the immune system, on the other hand some forms of CAM produced a detrimental effect on the virological suppression, opening this platform to more research and investigation in order to optimize the use of CAM among patients with HIV/AIDS.
