Background: Inferior myocardial infarction (MI) with right ventricular (RV) involvement will increase mortality and morbidity. Data of systolic and diastolic RV function in inferior ST-segment elevation MI (STEMI) are useful to predict the RV involvement.  Aims: To evaluate the prognostic and diagnostic significance of RV systolic and diastolic function compared to RVMI diagnostic criteria by electrocardiography in inferior MI patients.Methods: Consecutive patients with first, acute, inferior STEMI were prospectively assessed. The RVMI was defined as an ST-segment elevation ≥ 0.1 mV in lead V4R. Echocardiography was performed within 24 hours of the inferior STEMI symptoms. We assessed the RVMI diagnostic criteria in inferior MI patients using echocardiography.Results: Out of 31 patients (mean age 56.39 ± 9.02 years), RVMI by electrocardiography and echocardiography was found in 18 (37%). Moreover, multivariate analysis showed that two variables — RV systolic and diastolic function, were independent predictors of RVMI in inferior MI patients. Sensitivity and specificity of the RV systolic function were 94.4% and 69.2%, respectively, while RV diastolic functions were 44% and 76.9%, respectively.Conclusion: RV systolic function predict RVMI with relatively high sensitivity and specificity. RV diastolic function predicts RVMI with relatively low sensitivity but with high specificity.

Right ventricular (RV) involvement increases mortality and morbidity in inferior myocardial infarction (MI). There are sparse data on the usefulness of pulsed tissue Doppler imaging (TDI) in the diagnosis of RV dysfunction in ST segment elevation MI (STEMI). This study evaluate the diagnostic and prognostic significance of RV systolic and diastolic function compared to classical electrocardiographic RVMI diagnostic criteria in this group of patients. Consecutive patients with first, acute, inferior STEMI were prospectively assessed. The RVMI was defined as an ST-segment elevation ≥ 0.1 mV in lead V4R. Echocardiography with TDI was performed within24 h of the onset of symptoms. Out of 31 patients (mean age 56.39 ± 9.02 years), RVMI was found in 18 (37%). Multivariate analysis showed that two variables—RV systolic and diastolic function, were independent predictors of in-hospital prognosis. Sensitivity and specificity the RV systolic function were 94,4% and 69,2%, respectively. While RV diastolic function were 44% and 76,9%, respectively. RV systolic function predict ECG diagnosis of RVMI with relatively high sensitivity and specificity. RV diastolic function predict ECG diagnosis of RVMI with relatively low sensitivity but with high specificity.Keywords: tissue Doppler imaging, RV myocardial infarction, inferior myocardial infarction

Background: The ECG diagnosis of acute posterior infarction has traditionally been based on the presence of ST segment depression on the pericardial chest leads. However, such ST segment depression is neither specific nor sensitive for the diagnosis of a posterior infarction. Detection of ST segment elevation in V7- V9 in 15 lead ECG can help in early diagnosis of acute Posterior myocardial infarction. Method: Total of 100 patients Inferior myocardial infarction was evaluated by Electrocardiography in standard 12 lead and 15 lead. The patients were categorized into group I having posterior/ and or associated changes and group II having without posterior changes in ECG. Echocardiography and LVgraphy was done to evaluate the posterior wall movement. Result: For diagnosis of posterior myocardial infarction, 43.3% sensitivity and 95.1% specificity was found in 12 lead ECG, whereas in 15 lead ECG it was 80.0% sensitivity and 95.1% specificity. Conclusion: 15 Lead ECGs (including V7-V9) more sensitive than 12 lead ECGs in diagnosis of acute posterior myocardial infarction. Patient with inferior myocardial infarction or anterior ischemia developed more complications if associated with acute posterior myocardial infarction. 15 lead ECGs can routinely be used in patients with ischaemic type of chest pain.

Patients of acute inferior myocardial infarction, in addition to the ST segment elevation in inferior leads often have ST segment depression in the precordial leads. This study was performed to observe the incidence of these ‘reciprocal’ ST changes. One hundred consecutive acute inferior myocardial infarction patients were included in the study. They were further allocated to two electrocardiographic groups. Group 1 consisted of patients of acute inferior myocardial infarction with precordial ST segment depression & Group 2 consisted of patients of acute inferior myocardial infarction without precordial ST segment depression. Among the 100 consecutive patients, a large number of patients were included in group 1 (76%). Significant number of patients of group 1 belonged to the age group of above 60 years compared to group 2 (27.6% vs. 4.2%; p < .02). Conversely significantly higher number of younger patients ≤ 40 years belonged to group 2 (41.7% vs. 11.9%; p < .01). Mean ST segment elevation (mm) was also significantly higher in group 1 than group 2 (4.07 ± 1.93 vs. 2 ± 0.78; p <.001). The patients of acute inferior myocardial infarction thus show a significant number of ST segment depression in their precordial leads. In different studies these subset of patients showed increased morbidity and mortality. Key words: acute inferior myocardial infarction; precordial ST segment depression.

Introduction: In spite of the enormous progress made over the last decades, acute coronary syndromes remain the leading cause of death globally. Inflammation plays an important role in coronary artery disease development. Although the role of inflammatory biomarkers in acute obstructive myocardial infarction is well established, there is no data regarding the potential differences between acute myocardial infarction (AMI) with ST segment elevation, AMI without ST segment elevation (NON-STEMI) and non-obstructive acute myocardial infarction (MINOCA), respectively. Also, it is well known that cardiac rehabilitation of acute myocardial infarction survivors significantly improves their long-term prognosis. Aim of the study: To asses the possible existing differences between patients with STEMI, NON-STEMI and MINOCA in terms of clinical and paraclinical parameters, especially inflammatory biomarkers. A second objective of our study was to describe the relationship between inflammatory, cardiac necrosis enzymes and left ventricle systolic function. Material and methods: The study included 35 adult patients admitted in the Cardiology service of the Niculae Stăncioiu Heart Institute, Cluj-Napoca with acute myocardial infarction. Demographic, clinical, echocardiographic and laboratory data were analyzed. Patients were divided into 3 groups, 19 patients (54.2%) were diagnosed with STEMI- group 1, 9 patients (25.7%) with NON-STEMI- group 2 and 7 patients (20%) with MINOCA- group 3, respectively. Dosage of serum inflammatory markers was performed on the day of admission. Results and conclusion: The most common associated cardiovascular risk factor was arterial hypertension (65.7% of patients). Markers of myocardial necrosis (CK, CK-MB, hs Troponin) were significantly higher in patients with STEMI (p <0.05) in comparison with NON-STEMI and MINOCA patients. Congestive heart failure was most frequently encountered in STEMI patients. hsCRP value was higher among patients with STEMI. The value of ESR was significantly higher among patients with NON-STEMI. Serial dosage of inflammation biomarkers in patients with recent acute myocardial infarction may serve as valuable risk stratification instruments and also for functional capacity and recovery status assessment in patients included in cardiac rehabilitation programs.
