The presence of fQRS is a predictor in ST-elevation myocardial infarction patients undergoing p-PCI. The occurrence of fQRS is beneficial to identify the patients with severe coronary lesion, left ventricular contraction dysfunction, and larger areas of ischemic injury.

Atrial fibrillation (AF) is a highly prevalent condition associated with pronounced cardiovascular-related morbidity, mortality and socioeconomic burden. It accounts for more hospitalization days than does any other arrhythmia. This article reviews the basic electrophysiology of AF, electrical and structural remodeling in AF and recent advances in understanding the molecular mechanisms of AF in relation to specific microRNAs. This paper also reviews the potential role of microRNAs as novel therapeutic targets as well as biomarkers in the management of AF. AF shows characteristics typical of altered electrophysiology that promote ectopic activity and facilitate reentry, thereby contributing to the progression from short paroxysmal AF to a persistent, permanent form via atrial remodeling, even in the absence of progressive underlying heart disease. MicroRNAs have been suggested to influence the development of AF by regulating gene expression at the post-transcriptional level. Increasing evidence has identified various microRNA modifications and their impacts on AF initiation and maintenance through electrical and structural remodeling. The discovery of specific microRNAs as novel therapeutic targets and some experimental evidence implicating microRNAs as potential molecular diagnostic markers have had a significant impact on the diagnosis and management of AF and demand further research.

To compare the changes in blood glucose level associated with administration of adrenaline containing local anesthetic in diabetic and non-diabetic patients undergoing minor oral surgical procedures. METHODS AND MATERIAL The study included 150 well controlled diabetic patients and 150 non-diabetic healthy patients in age group of 40-60 years who underwent minor oral surgical procedures (trans alveolar extractions, alveoplasty and flap surgeries). Patients in both the group were administered 1.8ml of local anesthetic agent containing 1:100,000 adrenaline for inferior alveolar nerve block and 0.2 ml of anesthetic agent for long buccal nerve block. Blood glucose levels were assessed and compared during pre-operative and one hour post-operative period. STATISTICAL ANALYSIS The comparison of the random blood sugar levels preop and postop in both the groups were compared using paired t test and RBS levels between two groups were analysed using unpaired t test. P value less than 0.05 was considered statistically significant. RESULTS No statistically significant change in post-operative blood glucose level was noted between the diabetic and non-diabetic patients. CONCLUSION The study concluded that it is safe to administer local anesthetic containing 1:100,000 adrenaline in smaller volumes to well controlled diabetic patients.
