RESUMEN
In patients with acute heart failure (AHF), hemoconcentration has been suggested as a surrogate for volume changes (AHF). However, literatures comparing the outcome of AHF patients that achieved hemoconcentration during hospitalization with those that do not are limited. The aim of this research is to see if achieving hemoconcentration prior to discharge is linked to a lower risk of re-admission in AHF patients. 124 patients hospitalized in the Cardiology Unit, University Malaya Medical Centre (UMMC) for AHF between November 2019 and November 2020 were enrolled. Information on patients' clinical characteristics, laboratory values and in-hospital treatments were collected through electronic medical record. At admission and discharge, the change in hematocrit (HCT) levels was calculated, and patients were stratified based on two quantiles of delta HCT, either discharged with hemoconcentration (ΔHCT >1.5%) or without hemoconcentration (ΔHCT ≤1.5%). The study's outcome was AHF readmission after a 90-day follow-up period. Readmission was significantly associated with ejection fraction (p = 0.032) and HCT change (p = 0.005). Consecutively, logistic regression performed revealed that patients with haemoconcentration were 78.3% less likely to be readmitted than those without haemoconcentration (OR = 0.217, p = 0.003, 95% CI = 0.078-0.605) and Patients with a lower ejection fraction have a threefold greater chance of being readmitted than those with a preserved ejection fraction (OR = 3.316, p = 0.022, 95% CI = 1.188-9.256). In conclusion, among patients hospitalized and discharged for AHF, those that (i) do not achieve haemoconcentration and (ii) patients with a reduced ejection fraction were more likely to be readmitted with acute heart failure. Therefore, optimising patients' haematocrit levels prior to discharge may potentially reduce rehospitalizations among heart failure patients.

Background: Atorvastatin and sacubitril/valsartan (Entresto™) have been cornerstones in managing patients with coronary artery disease and heart failure (HF). We report a case of life-threatening rhabdomyolysis associated with the co-administration of atorvastatin and sacubitril/valsartan. Case summary: A 58-year-old male with coronary heart disease and chronic HF treated with the optimal dose of atorvastatin and other cardiovascular medications was frequently admitted for acute decompensation of HF. We decided to optimize his condition by adding sacubitril/valsartan to his treatment regime. He presented to our outpatient clinic with worsening myalgia and oliguria 6 days later. He was readmitted with markedly elevated serum creatinine kinase (CK) (94â850 U/L; normal range 32-294 U/L), deranged liver function tests, and acute kidney injury. We withheld atorvastatin and sacubitril/valsartan and treated him with renal replacement therapy. Discussion: Sacubitril inhibits the excretion of statins, thereby elevating serum statin concentration and increasing the likelihood of developing muscle-related toxicity. Co-administration of atorvastatin and sacubitril/valsartan should be monitored closely with laboratory investigations of CK and liver and renal function. The physician may consider starting low-dose atorvastatin at 20 mg daily in combination with sacubitril/valsartan 24 mg/26 mg twice daily and titrating accordingly to optimal doses. Rosuvastatin could be an alternative to atorvastatin, as it has less drug-drug interaction with sacubitril, thereby reducing the adverse effect.
RESUMEN
INTRODUCTION: Clinical depression is a known consequence of acute coronary syndrome (ACS) and is associated with an adverse outcome among these patients, although this is often under-recognised. Through this study, we investigated the incidence of depression in post-ACS patients and its associated factors. METHODS: We conducted a prospective cohort study in 95 patients with ACS admitted to University Malaya Medical Centre, Malaysia. Clinical depression was assessed during the index admission and at 30 days after discharge, using the Patient Health Questionnaire-9 (PHQ-9). Data was analysed using IBM SPSS Statistics, and binary logistic regression was used to determine the independent factors associated with depression, after adjusting for significant demographic variables and clinical characteristics. The strength of this association was presented as odds ratio and 95% confidence interval, and the significance level was set at 0.05. RESULTS: The mean age of the study population was about 60 years, and 72.6% of the patients were male. Symptoms of depression were present in 88.4% of the patients at baseline. Depression at 30 days was more likely in female patients, patients with diabetes mellitus and patients on dialysis (p = 0.024, p < 0.001, p = 0.008, respectively). Patients with baseline moderate to severe depression were more likely to have moderate to severe depression at 30 days (p < 0.001). Baseline depression was the strongest predictor of depression at 30 days. An increment of one unit in PHQ-9 baseline score increased the risk of developing severe depression at 30 days by 31%. CONCLUSION: Depression was prevalent in our post-ACS patients. The associated factors were female gender, diabetes mellitus and dialysis treatment.

Pulmonary nocardiosis is a rare disorder that mainly affects immune-compromised patients. We report a 37-year-old male who presented with persistent fever associated with productive cough. During this course of therapy, he had recurrent admissions for empyema thoracic. Clinically, his vital signs were normal. Blood investigations show leukocytosis with a significantly raised erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Sputum acid-fast bacilli (AFB) was scanty 1+ and sputum mycobacterium culture was negative. Chest X-ray (CXR) showed consolidative changes with mild to moderate pleural effusion on the right side. Skin biopsy was taken and showed Paecilomyces species. A computed tomography scan (CT thorax) was performed and revealed a multiloculated collection within the right hemithorax with a split pleura sign. Decortications were performed and tissue culture and sensitivity (C+S) growth of Nocardia species. And it is sensitive to sulfamethoxazole-trimethoprim and completed treatment for 4 months. This case highlights that pulmonary nocardiosis should be kept in mind in also immune-competent patients, especially in suspected cases of tuberculosis not responding to antitubercular therapy.
RESUMEN
OBJECTIVES: Cardiogenic shock (CS) complicating ST-elevation myocardial infarction (STEMI) carries an extremely high mortality. The clinical pattern of this life threatening complication has never been described in Malaysian setting. This study is to investigate the incidence, clinical characteristics and outcome of STEMI patients with CS in our population. DESIGN: A retrospective analysis of STEMI patients from 18 hospitals across Malaysia contributing to the Malaysian National Cardiovascular Database-acute coronary syndrome) registry (NCVD-ACS) year 2006-2013. PARTICIPANTS: 16 517 patients diagnosed of STEMI from 18 hospitals in Malaysia from the year 2006 to 2013. PRIMARY OUTCOME MEASURES: In-hospital and 30 day post-discharge mortality. RESULTS: CS complicates 10.6% of all STEMIs in this study. They had unfavourable premorbid conditions and poor outcomes. The in-hospital mortality rate was 34.1% which translates into a 7.14 times mortality risk increment compared with STEMI without CS. Intravenous thrombolysis remained as the main urgent reperfusion modality. Percutaneous coronary interventions (PCI) in CS conferred a 40% risk reduction over non-invasive therapy but were only done in 33.6% of cases. Age over 65, diabetes mellitus, hypertension, chronic lung and kidney disease conferred higher risk of mortality. CONCLUSION: Mortality rates of CS complicating STEMI in Malaysia are high. In-hospital PCI confers a 40% mortality risk reduction but the rate of PCI among our patients with CS complicating STEMI is still low. Efforts are being made to increase access to invasive therapy for these patients.

OBJECTIVE: Young women form a minority but an important group of patients with acute myocardial infarction (MI) as it can potentially cause devastating physical and socioeconomic impact. This study was aimed to investigate the characteristics and outcomes of young women with MI in Malaysia. DESIGN: This is a retrospective analysis of women with ST-elevation MI (STEMI) and non-STEMI (NSTEMI) from 18 hospitals across Malaysia using the Malaysian National Cardiovascular Database registry-acute coronary syndrome (NCVD-ACS). PARTICIPANTS: Women patients diagnosed with acute MI from year 2006 to 2013 were identified and divided into young (age ≤ 45, n=292) and older women (age >45, n=5580). PRIMARY OUTCOME MEASURE: Comparison of demographics, clinical characteristics and in-hospital management was performed between young and older women. In-hospital and 30-day all-cause mortality were examined. RESULTS: Young women (mean age 39±4.68) made up 5% of women with MI and were predominantly of Malay ethnicities (53.8%). They have a higher tendency to present as STEMI compared with older women. Young women have significantly higher rates of family history of premature coronary artery disease (CAD) (20.5% vs 7.8% p<0.0001). The prevalence of risk factors, such as hypertension, diabetes and dyslipidaemia was high in both groups. The primary reperfusion strategy was thrombolysis with no significant differences observed in the choice of intervention for both groups. Other than aspirin, rates of prescriptions for evidence-based medications were similar with >80% prescribed statins and aspirin. The all-cause mortality rates of young women were lower for both in-hospital and 30 days, especially in those with STEMI with adjusted mortality ratio to the older group, was 1:9.84. CONCLUSION: Young women with MI were over-represented by Malays and those with a family history of premature CAD. Preventive measures are needed to reduce cardiovascular risks in young women. Although in-hospital management was similar, short-term mortality outcomes favoured young compared with older women.
