Diagnostic Accuracy of Platelet/Lymphocyte Ratio for Screening Complex Coronary Lesion in Different Age Group of Patients with Acute Coronary Syndrome.

BACKGROUND: with the increasing number of patients with acute coronary syndrome (ACS) with complex coronary lesion and the increasing needs of coronary artery bypass grafting (CABG) procedures, there is an increasing need for a tool to perform early stratification in high-risk patients, which can be used in daily clinical practice, even at first-line health care facilities setting in Indonesia. It is expected that early stratification of high-risk patients can reduce morbidity and mortality rate in patients with ACS. This study aimed to identify diagnostic accuracy of platelet/lymphocyte ratio (PLR) and the optimum cut-off point of PLR as a screening tool for identifying a complex coronary lesion in patients ≤45 and >45 years old. METHODS: this was a retrospective cross-sectional study, conducted at the ICCU of Cipto Mangunkusumo Hospital. Data was obtained from medical records of adult patients with ACS who underwent coronary angiography between January 2012 - July 2015. The inclusion criteria were adult ACS patients (aged ≥18 years old), diagnosed with ACS and underwent coronary angiography during hospitalization. Diagnostic accuracy was determined by calculating sensitivity, specificity, positive likelihood ratio (LR+), and negative likelihood ratio (LR-). The cut-off point was determined using ROC curve. RESULTS: the proportion of ACS patients with complex coronary lesion in our study was 47.2%. The optimum cut-off point in patients aged ≤45 years was 111.06 with sensitivity, specificity, LR+ and LR of 91.3%, 91.9%, 11.27 and 0.09, respectively. The optimum cut-off points in patients aged >45 years was 104.78 with sensitivity, specificity, LR+ and LR of 91.7%, 58.6%, 2.21 and 0.14, respectively. CONCLUSION: the optimum cut-off point for PLR in patients aged ≤ 45 years is 111.06 and for patients with age >45 years is 104.78 with diagnostic accuracy, represented by AUC of 93.9% (p<0.001) and 77.3% (p<0.001), respectively for both age groups.

The Ability of Detecting Heart Rate Variability with the Photoplethysmography to Predict Major Adverse Cardiac Event in Acute Coronary Syndrome.

AIM: to assess heart rate variability (HRV) measurements using pulse photoplethysmograph (PPG) in predicting major adverse cardiac event (MACE) in acute coronary syndrome (ACS) patients. METHODS: a prospective cohort study was conducted among hospitalized ACS patients. Heart rate variability as predictor was measured by PPG within 48 hours after admission and the incidence of MACE as outcome was identified during ICCU stay. The ability of HRV in predicting MACE during hospitalization was determined by area under ROC curve (AUC) of low frequency (LF), high fequency (HF), and LF/HF ratio parameters. RESULTS: among 75 subjects included in the study, 14 (18.7%) were experienced MACE during hospitalization. HRV parameters of LF and LF/HF ratio have AUC of 0.697 (95% CI, 0.543-0.850) and 0.851 (0.741-0.962), respectively. Using cut-off point of 89.673 ms2, LF had PPV and NPV of 13% and 71%, respectively; while LF/HF ratio of 1.718 had PPV and NPV of 6% and 50%, respectively. CONCLUSION: the HRV parameters of LF and LF/HF ratio are moderate predictors for MACE and predict better ACS patients who will not develop MACE during hospitalization.

Ebstein Anomaly in Pregnancy.

A 27-year-old primiparous woman with 28 weeks gestational age was admitted to our hospital with worsening shortness of breath. She was diagnosed with Ebstein's anomaly three years ago, but preferred to be left untreated. The patient was not cyanotic and her vital signs were stable. Her ECG showed incomplete RBBB and prolonged PR-interval. Blood tests revealed mild anemia. Observation of two-dimensional echo with color flow Doppler study showed Ebstein's anomaly with PFO as additional defects, EF of 57%, LV and LA dilatation, RV atrialization, severe TR, and moderate PH with RVSP of 44.3 mmHg. The patient then underwent elective sectio caesaria at 30 weeks of gestational age; both the mother and her baby were alive and were in good conditions. PROBLEM: there was an increasing breathlessness in this patient so that there was an increasing need to take a decision for her pregnancy.Ebstein's anomaly is a complicated congenital anomaly. Medical treatment may be followed for many years in patients with mild forms of Ebstein's anomaly. Surgery should be considered if there is objective evidence of debasement such as significant enlargement of heart size, reduction of systolic function in echocardiography.

Hyperuricemia as a Risk Factors of Major Adverse Cardiac Events in Patients with Acute Coronary Syndrome: a Retrospective Cohort Study.

AIM: to investigate the MACE-free survivals difference between hyperuricemic and normouricemic patients and to determine its role as risk factor for MACE occurrence in hospitalized acute coronary syndrome patients. METHODS: retrospective cohort study with survival analysis approach was conducted in 251 patients with acute coronary syndrome who were treated in ICCU Cipto Mangunkusumo Hospital during period from January 2009 to December 2011. Clinical data, laboratory results, electrocardiography result, echocardiography result, and coronary angiography were collected. Patients were observed and followed on major adverse cardiac event during 7 days of hospitalization in ICCU. Major adverse Cardiac Event is an event as a complication occur after acute coronary syndrome such as cardiogenic syock, acute heart failure, stoke, reinfarct during early ward treatment, sudden cardiac death, repeat PCI during ward ulang and perform coronary artery bypass graft (CABG) surgery. Difference in survival is shown in Kaplan-meier curve and difference in survival between groups were tested with Log-rank test, and multivariate analysis with Cox proportional hazard regression to calculate adjusted HR on major adverse cardiac event with confounding variables as covariates. RESULTS: there was a significant difference in survival between hyperuricemia group and non-hyperuricemia group (Log-rank test (p<0.001)) with crude HR 2.7 (CI 95% 1.6-4) and adjusted HR 2.67 (CI 95% 1.6-4.3).There was significant difference in survival between hyperuricemia group (mean survival 6.05 days with SE 0.2 (CI 95% 5.6-6.4) and non-hyperuricemia group (mean survival 7.33 days with SE 0.1 (CI 95% 7.0-7.6). CONCLUSION: survival of patients suffering from ACS with hyperuricemia is worse compared to those without hyperuricemia during ICCU hospitalization.

The Influence of Hyperglycemia at Admission on In-hospital Arrhythmia Patients with Acute Coronary Syndrome.

AIM: to determine the incidence of in-hospital arrhythmias in patients with acute coronary syndrome (ACS) and to determine the influence of hyperglycemia at admission (HA) on in-hospital arrhythmias complicating ACS. METHODS: a retrospective cohort study was conducted using secondary data from medical records of patients with ACS who were admitted to ICCU RSCM, between January 1st-December 31st, 2014. Hyperglycemia at admission was defined when the blood glucose level at admission was >140 mg/dL. The in-hospital arrhythmias encompassed atrial arrhythmia, supraventricular tacchycardia (SVT), high grade AV block (HAVB), and ventricular arrhythmia, during the first seven days of hospitalization. RESULTS: there were 232 subjects in this study. The prevalence of HA was 50.43%. The incidence of in-hospital arrhythmia was 21.55% (95% CI 16.26-26.84). In bivariate analysis, there was significant association between HA and in-hospital arrhythmia (RR 1.75; 95% CI 1.04-2.93). There were no association between type of ACS, diabetes mellitus (DM), obesity, and hypertension, with the in-hospital arrhythmias. In multivariate analysis, the adjusted OR of HA was 2.85 (95% CI 1.35-6.02), and DM was the confounding variable. CONCLUSION: the incidence of in-hospital arrhythmias in patients with ACS was 21.55% (95% CI 16.26-26.84). Hyperglycemia at admission may increase the risk of in-hospital arrhythmia in patients with ACS.

Underutilization of anticoagulant for venous thromboembolism prophylaxis in three hospitals in Jakarta.

AIM: to assess the current use of anticoagulants and implementation of International Guidelines in venous thromboembolism (VTE) prophylaxis in hospitalized patients with acute medical illnesses in Jakarta, Indonesia. METHODS: a multicenter, prospective, disease registry, recruiting patients diagnosed as acutely ill medical diseases and other medical conditions at risk of VTE, with in-hospital immobilization for at least 3 days. RESULTS: of 401 patients, 46.9% received anticoagulants which included unfractionated heparin (64.4%), fondaparinux (11.7%), enoxaparin (9.6%), warfarin (3.7%), and combination of anticoagulants (10.6%). VTE prophylaxis using physical and mechanical method was used in 81.3% of patients, either as a single modality or in combination with anticoagulants. During hospitalization, VTE were found in 3.2% patients; 10 patients (2.5%) had lower limb events and 3 patients (0.75%) had a suspected pulmonary embolism. The main reference international guidelines used were AHA/ASA 2007 (47.4%), followed by ACCP 2008 (21.7%). CONCLUSION: the study showed underutilization of prophylaxis anticoagulants in which mechanical thromboprophylaxis either alone or combination with anticoagulants was the most commonly used. Unfractionated heparin was the preferable choice. The most commonly used guideline was AHA/ASA 2007. VTE thromboprophylaxis in medically ill patients needs to be encouraged.
