The myocardial performance index (MPI) was assessed in 30 patients with limb girdle muscle dystrophy (LGMD) with a normal left ventricular ejection fraction (greater than 50%), as well as in 30 age-and sex-matched healthy adults with a left ventricular ejection fraction greater than 50%. MPIs derived by pulsed-wave Doppler and tissue Doppler were also compared. The MPI was 0.37±0.09 in the LGMD patients and 0.29±0.09 in the control group (P=0.003). These data show that patients with LGMD have occult cardiac dysfunction as evidenced by a higher MPI than the controls. There was good agreement between the MPIs measured by pulsed-wave Doppler and tissue Doppler methods in these patients.
Background: Compared to older counterparts, a significant distinction has been found related to risk factors, clinical presentation, and prognosis of ST-segment elevation myocardial infarction (STEMI) in younger patients. To date, a lack of studies has been looked, specifically at-risk factors and angiographic profile of STEMI among younger patients; with this in mind, we conducted the present study.Methods: This hospital-based, cross-sectional, open-label study was carried out at Deccan College of Medical Sciences between April 2018 and December 2019. Patients under 40 years with the presentation of STEMI were included. All patients were subjected to electrocardiography, 2D echocardiography, and coronary angiogram. Baseline demographics, risk factors, and procedural characteristics were recorded.Results: Of 51 young STEMI patients, 41 (80.4%) were male and 10 (19.6%) were female. The most common risk factors associated with the development of STEMI in young patients were smoking (58.8%), followed by diabetes (45.1%), and dyslipidaemia (45.1%). Anterior wall MI was the most frequent presentation (84.3%). The left anterior descending artery was the most frequently (62.8%) involved vessel, followed by left circumflex artery (9.8%), and right coronary artery (5.9%).Conclusions: Insights gained from the study can aid in identifying clinical characteristics of STEMI in young patients, which may be beneficial to achieve appropriate and timely management. Further, the young population should be educated as to control modifiable risk factors and smoking cessation to prevent coronary artery disease since they belong to the highly productive group in the community.
Background: The ST-elevation myocardial infarction (STEMI), a fatal disease, is rapidly extending in patients, worldwide. Therefore, proper and timely diagnosis followed by appropriate management becomes necessary. The study aimed to compare the effectiveness of metoprolol and ivabradine in acute STEMI patients.Methods: This was an observational, comparative, in-hospital study carried out in patients admitted in the in-patient cardiac department, intensive cardiac care unit of a tertiary care centre in India. Total 60 patients diagnosed with acute ST-elevation MI were included in the study and were equally divided into two groups. Group 1 involved patients who were given metoprolol for treatment and group 2 involved patients who were given ivabradine. The patients were assessed in terms of heart rate, NYHA class, and ejection fraction. Follow-up of 30 days was taken in all patients.Results: Ivabradine reduced mean heart rate from 85.57 bpm at baseline to 78.23 bpm. Heart rate in the metoprolol group was reduced from 81.93 bpm to 76.47 bpm over the same time period. Metoprolol and ivabradine showed significant improvement in the ejection fraction volume during the in-hospitalization stay. Ivabradine showed a better improvement in ejection fraction when compared to metoprolol but the difference was not found to be statistically significant. Higher mortality was assessed in ivabradine group compared to metoprolol.Conclusions: The study gives the gold standard efficacy and mortality benefit of metoprolol, although ivabradine on the other hand gave better responses in heart rate reduction and improvements in ejection fraction.
