We report a case of right bundle branch block, in which the patient’s symptoms and the electrocardiogram findings mimicked those of acute coronary syndrome. In this case report, we stress the significance of apparent ST segment elevation in right bundle branch block. The differential diagnosis is important because right bundle branch block is often complicated with acute coronary syndrome. In addition, right bundle branch block with an ST segment elevation in the specific leads can be a predictor of sudden cardiac death. In such cases, close monitoring of the electrocardiogram findings and careful observation of the patient’s symptoms would be necessary.

Background and aims: Acute coronary syndrome (ACS), which comprises acute ST-segment elevation myocardial infarction, non-ST segment elevation myocardial infarction and unstable angina is a major health problem and represents a large number of hospitalizations annually worldwide. We aim to describe pattern of the ACS admission and in-hospital mortality at tertiary national heart centre of the country. Methods: A hospital database was used to analyze all 7424 patients admitted in coronary care unit of the centre for ACS from September 2001 till December 2012. We evaluated trend of ACS admission and in-hospital mortality. Results: Five thousand three hundred ninety one (72.6%) were male and two thousand thirty three (27.4%) were female. Patient of 21years to 98 years were admitted for ACS .Four thousand five hundred and ninety nine(61.9%) patient were admitted due to ST elevation myocardial infarction, whereas one thousand nine hundred and thirteen (25.8%) were admitted for Unstable angina and nine hundred twelve (12.3%) were admitted for Non ST elevation myocardial infarction. In-hospital mortality was 5.74% for acute coronary syndrome. There was significant difference in in-hospital mortality between ST elevation myocardial infarction (7.76%), Non ST segment elevation acute coronary syndrome (3.61%) and Unstable Angina (1.88%).There is a gradual increase in Primary Percutaneous Coronary intervention as a mode of reperfusion therapy whereas there is a decrease in the rate of thrombolysis. Conclusion: Our study provides us some important information about the trend and in-hospital mortality rate in national heart centre. Though it is a single centre study can provide us the insight of the ACS outcome. DOI: http://dx.doi.org/10.3126/jaim.v3i1.10698 Journal of Advances in Internal Medicine 2014;03(01):23-26

Aims To investigate the different risk factors among different subtypes of patients with acute coronary syndrome (ACS). Methods A total of 296 patients who had ACS were retrospectively enrolled. Blood and echocardiographic indices were assessed within 24 hours after admission. Differences in risk factors and Gensini scores of coronary lesions among three groups were analyzed. Results Univariate analysis of risk factors for ACS subtypes showed that age, and levels of fasting plasma glucose, amino-terminal pro-brain natriuretic peptide, and creatine kinase isoenzyme were significantly higher in patients with non-ST-segment elevation myocardial infarction (NSTEMI) than in those with unstable angina pectoris (UAP). Logistic multivariate regression analysis showed that amino-terminal pro-brain natriuretic peptide and the left ventricular ejection fraction (LVEF) were related to ACS subtypes. The left ventricular end-diastolic diameter was an independent risk factor for UAP and ST-segment elevation myocardial infarction (STEMI) subtypes. The severity of coronary stenosis was significantly higher in NSTEMI and STEMI than in UAP. Gensini scores in the STEMI group were positively correlated with D-dimer levels (r = 0.429) and negatively correlated with the LVEF (r = −0.602). Conclusion Different subtypes of ACS have different risk factors. Our findings may have important guiding significance for ACS subtype risk assessment and clinical treatment.

Drugs that work on the hematologic system play an important role in helping to limit the morbidity and mortality that can be associated with an acute coronary syndrome. The pharmacology of the fibrinolytic agents, thrombin inhibitors, and antiplatelet agents is described. A case study of a woman having an ST-segment elevation myocardial infarction is reviewed to highlight the importance of drugs that work on the hematologic system.

Acute myocardial infarction is the leading cause of death in the world and the electrocardiogram remains the diagnostic tool for determining an acute myocardial infarction with ST-segment elevation. In spite of this, only half of the patients present classic electrocardiogram findings compatible with the ST-elevation infarction criteria. There is a spectrum of electrocardiographic findings that may reflect a phenomenon of acute coronary occlusion, which should be promptly recognized by the clinician to offer early reperfusion therapy.

Objectives: We sought to assess whether plasma neopterin predicts adverse clinical outcomes in patients with NSTEACS. Background: Circulating C reactive protein (CRP), a marker of inflammation, correlates with events in patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). High neopterin levels - a marker of macrophage activation - predict cardiovascular events in stable angina patients but their prognostic role in NSTEACS has not been systematically evaluated. Methods: We prospectively assessed 397 patients (74 % men) admitted with NSTEACS: 169 (42.5%) had unstable angina and 228 (57.5%) non-ST-segment elevation myocardial infarction (NSTEMI). Blood samples for neopterin and CRP assessment were obtained at admission. TIMI risk score was also assessed among other clinical and biochemical variables. The study end point was the composite of cardiac death, acute myocardial infarction and recurrent angina at 180-days. Results: Baseline neopterin concentrations (nmol/L) were similar in unstable angina and NSTEMI patients (8.3 [6.5–10.6] vs 8.0 [6.2–11.1], p = 0.54). Fifty-nine patients (14.9 %) had events during follow-up (highest third (%) 21.5 vs 1 st and 2 nd thirds 11.5, log rank 7.341, p = 0.007). On multivariable hazard Cox regression, only neopterin (highest vs 1 st and 2 nd thirds, HR 2.15, 95 % CI [1.21–3.81]) was independently associated with the combined endpoint.CRP levels, however, were not significantly different in patients with events compared to those without events (adjusted HR = 0.98, p = 0.89, 95% CI 0.80 –1.21). Conclusion: Increased neopterin levels are an independent predictor of 180-day adverse cardiac events in patients with NSTEACS.

Abstract The new European Society of Cardiology guideline for ST-segment elevation myocardial infarction recommends that left and right bundle branch block should be considered equal for recommending urgent angiography in patients with suspected myocardial infarction. This consideration is not taken into account in the management of patients with coronary syndrome without ST elevation (NSTEMI). We evaluate the evolution of patients with acute coronary syndrome and long-term bundle branch block. Patients and methods We included 8771 patients admitted to two tertiary hospitals between 2003 and 2017 with an acute coronary syndrome, 5673 NSTEMI (64.3%) and 3098 STEMI (35.7%). All patients had an ECG recorded immediately upon admission. Patients were classified as having right bundle branch block (RBBB), left bundle branch block (LBBB). Long-term follow-up was performed (median 55 months) to assess mortality. Results A total of 8771 patients were included with a mean age of 66.1 years, 72.5% males, 4.1% (362) with LBBB and 5% (440) with RBBB. Patients with BBB were older, with more previous history of myocardial infarction and coronary revascularization and higher prevalence of cardiovascular risk factors. Medical treatment was similar but they were less often submitted to angioplasty. During the acute phase, patients with RBBB and LBBB presented a higher rate of heart failure than those without branch block (4.8% vs 9.1% vs 3.5%, p=0.0001); higher mortality (8.4% vs 10.5% vs 3.0%, p=0.0001); higher stroke rate (2.5% vs 1.4% vs 0.8%, p=0.001); higher rate of renal failure (8.2% vs 9.7% vs 3.9%, p=0.0001) and higher rate of reinfarction (3.0% vs 4.1% vs 1.7%, p=0.001). Patients who had a RBBB or an LBBB had a worse prognosis throughout the follow-up. Heart failure was present in 17.7% of the group with RBBB, 29.6% of LBBB and 11% in the group without branch block (p=0.0001). Mortality during follow-up was 31% in RBBB, 40.6% in LBBB and 18.7% without branch block (p=0.0001). In multivariate analysis of Cox, both RBBB (HR 1.55, 95% CI 1.23–1.98, p=0.0001) and LBBB (HR 1.48, 95% CI 1.22–1.53, p=0.001) were an independent predictors of all-cause mortality (adjustment for GRACE score, gender, treatment with betablockers, angiotensin conversor enzym inhibitors, statin and coronary revascularization). Cox regression model multivariate Conclusions The presence of RBBB or LBBB in the ECG of patients with an ACS is associated with a worse prognosis both during the hospital phase and in the long term. In addition, both bundle branch blocks are independent predictors of long-term mortality in patients with ACS.
