ABSTRACT
Aim: To address the existing gaps in knowledge about long-acting nitroglycerine (LA-NTG) and provide recommendations to address these issues. Methodology: Approved LA-NTG questionnaire that included 17 questions related to the role of LA-NTG in the management of angina and chronic coronary syndrome (CCS) was shared with 150 expert cardiologists from different regions from India. Results of these survey questionnaires were further discussed in 12 regional level meetings. The opinions and suggestions from all the meetings were compiled and analyzed. Further, recommendations were made with the help of attending national cardiology experts and a consensus statement was derived. Results: This is the first consensus on LA-NTG, summarizing the clinical evidence from India and suggesting recommendations based on these data. The experts recommended early use of LA-NTG as a first-line antianginal therapy in combination with beta-blocker since it improves exercise tolerance in patients with CCS. A strong consensus was observed for using LA-NTG in patients with co-morbid hypertension, diabetes, chronic kidney disease and post-percutaneous coronary intervention angina. As a part of cardiac rehabilitation, LA-NTG allows patients with angina to exercise to a greater functional capacity. Conclusions: A national consensus was observed for several aspects of LA-NTG in the management of angina and CCS. The clinical experience of the experts confirmed an extremely satisfied patient perception about the efficacy of LA-NTG.
ABSTRACT
BACKGROUND: This study was conducted to assess the safety and feasibility of a transulnar approach in performing diagnostic and interventional percutaneous coronary procedures. METHODS AND RESULTS: In the year 2004, a total of 100 patients underwent diagnostic angiography (n=64) and percutaneous coronary interventions (n=36) through transulnar approach. The patients' age ranged from 40 to 70 years and male to female ratio was 7.3:1. The cases of percutaneous coronary interventions were mostly elective procedures and emergency intervention was done in only 2 patients. The procedure was successful in 95 (95%) patients and unsuccessful in 5 (4 diagnostic and 1 percutaneous coronary intervention). The procedure was done through right ulnar artery in all except one patient in whom it was done through left ulnar artery. The total procedure time ranged between 25-45 min. Among the cases of percutaneous coronary interventions, single vessel angioplasty was performed in 23 (65.7%) patients, double vessel in 11 (31.4%) patients and triple vessel in 1 (3%) patient. All percutaneous coronary intervention patients received aspirin, clopidogrel and intravenous enoxaparin. Glycoprotein IIb/IIIa inhibitors were used in 7 patients. Complications such as local hematoma, ulnar artery perforation and reversible parasthesia occurred in one patient each. CONCLUSIONS: Tansulnar approach is a safe and easy alternative technique to perform diagnostic and therapeutic coronary interventions.
