Outcomes of Smoking Cessation in Post-Ischemic Heart Diseases

Abstract

Background:Tobacco intake is related to an increased risk of stroke in subjects consuming it, and this increase is directly dependent on the dose of Tobacco being taken. Tobacco alone is documented to be the reason for approximately 12% to 15% of the stroke patients reported to medical care. Aim:The present study was aimed to evaluate the outcomes of smoking cessation after ischemic heart diseases. Materials and Methods: The study included 120 subjects who were followed for 1 year at the interval of 3 months, 6 months, and 12 months. Following parameters were assessed at all the recall intervals: Risk of outcomes for stroke, MI, and mortality depending on the smoking state, and reason for mortality in deceased. All the collected were subjected to statistical evaluation (95% Confidence Interval). Results: After the ischemic disease episode, out of the included 120 subjects 40% (n=48) quitted smoking whereas 60% (n=72) continued smoking after ischemic heart disease. It was seen that for MI there was significantly more risk in continued smokers at all the time intervals with the p-value of < 0.0001. Concerning stroke similar results were seen0.0002, 0.0116, 0.0023, and < 0.0001 respectively at consecutive recalls. Regarding death, significantly lesser deaths were seen in the quitters.In deceased subjects, it was seen that the highest number of death was reported by cardiovascular diseases in continued smokers. Conclusion:The present study concludes that smoking cessation has positive outcomes in subjects after ischemic heart diseases in terms of reduced risk of developing future diseases like MI and stroke significantly. Also, smoking cessation, lead to a reduction in the rate of mortality in a 12 month follow up in the present study
