Objective: To determine the prevalence of first diagnosed atrial fibrillation in patients admitted with acute coronary syndrome and with impaired renal function with and without diabetes mellitus. Methodology: A total of 434 patients were selected from two different hospitals, 361 from NICVD, Tando Muhammad Khan and 73 from Isra University Hospital, Hyderabad. Both males and females, aged between 18 years to 70 years, first ever presented & admitted with acute coronary syndrome (ACS) and renal impairment were included and whereas, patients with atrial fibrillation (AF) other than first diagnosed, previous history of myocardial infarction/coronary artery bypass grafting (CABG), known case of chronic kidney disease/on dialysis, history of cerebrovascular accident (CVA), patient with valvular heart disease, and pregnant women were excluded from this study. Baseline and clinical data was collected to determine the association with the prevalence of first diagnosed AF through chi-square test and a p value of <0.05 was considered as statistically significant. Results: The mean age ± SD was 49.32±12.47 years. Among them majority were males 66.35% and rural residents 51.15% respectively. The most common risk factor observed in our study was presence of hypertension (N = 231, 53.22%) and among all ACS patients, most common type of ACS was unstable angina (N = 195, 44.93%). The overall prevalence of first diagnosed atrial fibrillation was 12.44% (N = 54) and the overall prevalence of diabetes mellitus was 39.63% (N = 172). Mean random blood sugar levels in diabetic patients was 203.32±105.60 mg/dL, hypertensive patients with DM (48.14%), and patients with STEMI with DM (12.96%) were significantly associated with increased prevalence of first diagnosed atrial fibrillation, p value <0.05. Conclusion: Prevalence of first diagnosed AF is comparatively higher in our study because of the underlying renal impairment. Modifiable risk factor like uncontrolled blood sugar levels has significance association with first diagnosed AF.

SummaryChronic Kidney Disease (CKD) constitutes an adverse risk factor in chronic anticoagulated atrial fibrillation (AF) patients, being related to adverse cardiovascular events, mortality and major bleeds. It is unclear if CKD adds independent prognostic information to stroke risk stratification schemes, as the risk factor components of the CHADS2 and CHA2DS2-VASc scores are themselves related to renal dysfunction. The aim of our study was to determine if CKD independently improves the predictive value of the CHADS2 and CHA2DS2-VASc stroke stratification scores in AF. We recruited consecutive patients (n=978) patients (49% male; median age 76) with permanent or paroxysmal AF on oral anticoagulants with acenocoumarol, from our out-patient anticoagulation clinic. After a median follow-up of 875 (IQR 706–1059) days, we recorded stroke/transient ischaemic attack (TIA), peripheral embolism, vascular events (acute coronary syndrome, acute heart failure and cardiac death) and all-cause mortality. During follow-up, 113 patients (4.82%/year) experienced an adverse cardiovascular event, of which 39 (1.66%/year) were strokes, 43 (1.83%/year) had an acute coronary syndrome and 32 (1.37%/year) had acute heart failure. Also, 102 patients (4.35%/year) died during the following up, 31 of them (1.32%/year) as a result of a thrombotic event. Based on c-statistics and the integrated discrimination improvement (IDI), CKD did not improve the prediction for stroke/systemic embolism, thrombotic events and all-cause mortality using the CHADS2 and CHA2DS2-VASc scores. In conclusion, evaluating renal function in AF patients is important as CKD would confer a poor overall prognosis in terms of thromboembolic events and all-cause mortality. Adding CKD to the CHADS2 and CHA2DS2-VASc stroke risk scores did not independently add predictive information.Note: The review process for this manuscript was fully handled by Christian Weber, Editor in Chief.

Abstract Background Antegradely conducting left lateral accessory pathways are a risk for supraventricular tachycardias and pre-excited atrial fibrillation. Rarely, an anomalous coronary sinus can cause difficulty in locating the pathway. The left circumflex coronary artery and obtuse marginal branches supply the posterolateral left ventricle. We describe a case report of a high-risk accessory pathway associated with an anomalous coronary sinus which, between successive electrophysiology studies, was obliterated by a felicitous acute coronary syndrome in the left circumflex territory. Case summary A 49-year-old male with palpitations and manifest pre-excitation was referred for electrophysiology study. Initial study revealed a high-risk left lateral accessory pathway with antegrade effective refractory period of 240 ms and rapidly conducting pre-excited atrial fibrillation. The coronary sinus could not be cannulated to localize the pathway. Coronary angiography and cardiac computed tomography showed an anomalous coronary sinus emptying into the right atrial free wall and patent coronaries. While awaiting repeat electrophysiology study, the patient suffered an acute coronary syndrome with immediate loss of previously visible pre-excitation on electrocardiogram, and underwent stenting of an occluded marginal branch of the circumflex. Repeat electrophysiology study demonstrated a now low-risk accessory pathway (effective refractory period 390 ms). Since infarction, the patient’s palpitations have fully settled with all subsequent electrocardiograms devoid of manifest pre-excitation. Discussion Left lateral accessory pathways, which can associate with an anomalous coronary sinus, derive from tissue similar to normal ventricular myocardium and are vulnerable to ischaemic insults in the area subtended by the circumflex artery.

ABSTRACT Myocardial bridging is an uncommon cause of a quite common emergency department complaint for chest pain and is often associated with left ventricular hypertrophy. We present a case of an otherwise healthy middle-aged U.S. military service member who presented with acute coronary syndrome which was ultimately determined to be the result of myocardial bridging.
