Distal Protection

Objective Embolization of material from an infarct-related lesion during percutaneous coronary intervention (PCI) may result in an increased infarct size. We evaluated the effect of distal protection during PCI for ST-segment elevation myocardial infarction (STEMI) on clinical outcome and myocardial function. Methods and results Patients with STEMI were randomly referred within 12 hours for PCI with (n = 312) or without distal protection (n = 314). Left ventricular (LV) contractile function was assessed with echocardiography 8 month after PCI. Global LV myocardial wall motion index (WMI) was calculated as the average wall motion score of all myocardial segments. Major adverse cardiac and cerebral events (MACCE) 8 months after PCI was 7.1 % after distal protection and 5.7 % after conventional treatment (p = 0.17). WMI improved by 4.1% at 8 months in patients treated with distal protection compared to patients receiving conventional PCI (p<0.01). In myocardium subtended by culprit coronary vessels treated with distal protection regional LV function was 9 –11% higher than myocardial regions treated conventionally (p<0.02). Conclusion Routine use of distal protection during primary PCI is associated with a significant improvement in LV contractile function, with no detectable impact on intermediate term clinical outcome.

Background: The effect of late percutaneous coronary intervention on left ventricular function is incompletely understood. Objectives: To evaluate the effect of late Percutaneous Coronary Intervention on LV systolic function following coronary stenting after acute anterior myocardial infarction. Methods: A total of 60 patients, > 24 hours to 6 weeks after anterior AMI who attended in UCC, BSMMU between July 2014 to June 2015 were included in this study. They underwent coronary stenting. After coronary stenting all patients were in TIMI flow-3. Serial echocardiographic assessment of LV function before and after late intervention with modified Simpson’s rule in apical 4 chamber view as well as comparison between baseline result with that of after intervention were done. The patients were on standard medical therapy in post intervention period. Result: Mean age was 54.3±8.91 years with minimum 30 years and maximum 75 years. Most of the patients were male (67%). LVESV was 60.0±14.4 ml before PCI and 58.3±15.3 ml at discharge (p value 0.091) & 44.1±17.6 ml after 3 months (p value <0.001). LVEF was 40.2±3.1% before PCI, 40.2±3.3% at discharge (p value 0.509) & 47.6±5.9% after 3 months (p value <0.001). There was no significant improvement of LV function from baseline till discharge but significant improvement occurred after 3months. Conclusion: Using echocardiographic techniques, our results showed that left ventricular volume decreased and the left ventricular ejection fraction increased significantly after three months of late intervention.

Coronary artery disease (CAD) is a spectrum of heart diseases which has the highest mortality in the world. Systolic left ventricular (LV) function is an important predictor of outcome, and its precise assessment remains of great importance for the choice of treatment in populations with myocardial infarction (MI). This study was aimed to assess the function and viability of ischemic myocardium of LV before and after the percutaneous coronary intervention (PCI) by using 2dimentional (2D) STE with LDDSE and to know the usefulness of low dose dobutamine (LDD) test in detecting the viable ischemic LV area. The results of the current study revealed there was a significant decrease (improvement) in GLS before dobutamine from (-10.49±3.4) to (-12.87±3.44) after dobutamine. Then there was a significant increase (deterioration) in GLS from (-12.87±3.44) after giving 5 mg/kg/min dobutamine to (-11.56±3.29) after giving 10 mg/kg/min dobutamine (P value < 0.001). While there were no significant differences in GLS after low dose dobutamine (-12.87±3.44) with the same parameters 3-6 months after PCI (-13.48±3.7). Left anterior descending artery (LAD) is the most common affected artery in our study. The study concluded that GLS provides a sensitive measure of LV function and appears reduced despite preserved LVEF also GLS can detect the viability of ischemic myocardium of LV with using LDD test which then assessed by PCI.

Background: Considering that contrast medium is excreted through the whole kidney in a similar manner to drug excretion, the use of raw estimated glomerular filtration rate (eGFR) rather than body surface area (BSA)-normalized eGFR is thought to be more appropriate for evaluating the risk of contrast-induced acute kidney injury (CI-AKI). Methods: This study included 2,189 myocardial infarction patients treated with percutaneous coronary intervention. Logistic regression analysis was performed to identify the independent risk factors. We used receiver-operating characteristic (ROC) curves to compare the ratios of contrast volume (CV) to eGFR with and without BSA normalization in predicting CI-AKI. Results: The area under the curve (AUC) of the ROC curve for the model including all the significant variables such as diabetes mellitus, left ventricular ejection fraction, preprocedural glucose, and the CV/raw modification of diet in renal disease (MDRD) eGFR ratio was 0.768 [95% confidence interval (CI), 0.720-0.816; p < 0.001]. When the CV/raw MDRD eGFR ratio was used as a single risk value, the AUC of the ROC curve was 0.650 (95% CI, 0.590-0.711; p < 0.001). When the CV/MDRD eGFR ratio with BSA normalization ratio was used, the AUC of the ROC curve further decreased to 0.635 (95% CI, 0.574-0.696; p < 0.001). The difference between the two AUCs was significant (p = 0.002). Conclusions: Raw eGFR is a better predictor for CI-AKI than BSA-normalized eGFR.

ABSTRACT EVALUATION OF HEART FAILURE IN ST - ELEVATED MYOCADIAL INFARCTION BEFORE AND AFTER PERCUTANEOUS CORONARY INTERVENTION Objectives: Assess the function of left ventricle in ST elevation myocardial infarction before, 48 - hour and 3 - month after primary percutaneous coronary intervention by cardiac ultrasound. Patients: 97 patients who underwent PCI for ST elevated myocardial infarction from 02/2021 to 09/2020. Methods: Prospective observational study. Results: Left ventricular mass index decreased from 195.2 ± 65.8 gr/m2 to 170.2 ± 51.1 gr/m2, end - diastolic left ventricular volume decreased from 105.2 ± 37.4 mm to 95.5 ± 41.3 mm. End systolic volume decreased from 57.3 ± 45.2 mm to 49.8 ± 50.3 mm. Ejection fraction 3 month after the intervention of the EF ≤ 45 % group significantly increased from 39.3 ± 11.2 % to 45.85 ± 7.56 % (p < 0.05). In contrast, there were a rise of the ejection fraction among the EF > 45% group from 57.7 ± 14.4% to 60.1 ± 13.3 % (p > 0.05). Conclusion: 3 month after PCI, left ventricular mass, end - systolic and diastolic volume changed remarkably. The ejection fraction of EF ≤ 45 % group increased with a statical significance.
