Double-Dose Versus Standard-Dose Clopidogrel According to Smoking Status Among Patients With Acute Coronary Syndromes Undergoing Percutaneous Coronary Intervention
Background: Prior Studies have suggested better outcomes in smokers compared with nonsmokers receiving clopidogrel (āsmoker's paradoxā). The impact of a more intensive clopidogrel regimen on ischemic and bleeding risks in smokers with acute coronary syndromes requiring percutaneous coronary interventions remains unclear. Methods and Results: We analyzed 17 263 acute coronary syndrome patients undergoing percutaneous coronary intervention from the CURRENTāOASIS 7 (Clopidogrel and Aspirin Optimal Dose Usage to Reduce Recurrent EventsāSeventh Organization to Assess Strategies in Ischemic Symptoms) trial, which compared doubleādose (600 mg day 1;150 mg days 2ā7; then 75 mg daily) versus standardādose (300 mg day 1; then 75 mg daily) clopidogrel in acute coronary syndrome patients. The primary outcome was cardiovascular death, myocardial infarction, or stroke at 30 days. Interactions between treatment allocation and smoking status (current smokers versus nonsmokers) were evaluated. Overall, 6394 patients (37.0%) were current smokers. For the comparison of doubleā versus standardādose clopidogrel, there were significant interactions in smokers and nonsmokers for the primary outcome (P=0.031) and major bleeding (P=0.002). Doubleā versus standardādose clopidogrel reduced the primary outcome among smokers by 34% (hazard ratio [HR] 0.66, 95% confidence interval [CI], 0.50ā0.87, P=0.003), whereas in nonsmokers, there was no apparent benefit (HR 0.96, 95% CI, 0.80ā1.14, P=0.61). For major bleeding, there was no difference between the groups in smokers (HR 0.77, 95% CI, 0.48ā1.24, P=0.28), whereas in nonsmokers, the doubleādose clopidogrel regimen increased bleeding (HR 1.89, 95% CI, 1.37ā2.60, P<0.0001). Doubleādose clopidogrel reduced the incidence of definite stent thrombosis in smokers (HR 0.41, 95% CI, 0.24ā0.71) and nonsmokers (HR 0.63, 95% CI, 0.42ā0.93; P for interaction=0.19). Conclusions: In smokers, a doubleādose clopidogrel regimen reduced major cardiovascular events and stent thrombosis after percutaneous coronary intervention, with no increase in major bleeding. This suggests that clopidogrel dosing in patients with acute coronary syndromes should be personalized, taking into consideration both ischemic and bleeding risk.

Comparison of heart team vs interventional cardiologist recommendations for the treatment of patients with multivessel coronary artery disease
Abstract: Importance: Although the heart team approach is recommended in revascularization guidelines, the frequency with which heart team decisions differ from those of the original treating interventional cardiologist is unknown. Objective: To examine the difference in decisions between the heart team and the original treating interventional cardiologist for the treatment of patients with multivessel coronary artery disease. Design, setting, and participants: In this cross-sectional study, 245 consecutive patients with multivessel coronary artery disease were recruited from 1 high-volume tertiary care referral center (185 patients were enrolled through a screening process, and 60 patients were retrospectively enrolled from the center's database). A total of 237 patients were included in the final virtual heart team analysis. Treatment decisions (which comprised coronary artery bypass grafting, percutaneous coronary intervention, and medication therapy) were made by the original treating interventional cardiologists between March 15, 2012, and October 20, 2014. These decisions were then compared with pooled-majority treatment decisions made by 8 blinded heart teams using structured online case presentations between October 1, 2017, and October 15, 2018. The randomized members of the heart teams comprised experts from 3 domains, with each team containing 1 noninvasive cardiologist, 1 interventional cardiologist, and 1 cardiovascular surgeon. Cases in which all 3 of the heart team members disagreed and cases in which procedural discordance occurred (eg, 2 members chose coronary artery bypass grafting and 1 member chose percutaneous coronary intervention) were discussed in a face-to-face heart team review in October 2018 to obtain pooled-majority decisions. Data were analyzed from May 6, 2019, to April 22, 2020. Main outcomes and measures: The Cohen Īŗ coefficient between the treatment recommendation from the heart team and the treatment recommendation from the original treating interventional cardiologist. Results: Among 234 of 237 patients (98.7%) in the analysis for whom complete data were available, the mean (SD) age was 67.8 (10.9) years; 176 patients (75.2%) were male, and 191 patients (81.4%) had stenosis in 3 epicardial coronary vessels. A total of 71 differences (30.3%; 95% CI, 24.5%-36.7%) in treatment decisions between the heart team and the original treating interventional cardiologist occurred, with a Cohen Īŗ of 0.478 (95% CI, 0.336-0.540; P = .006). The heart team decision was more frequently unanimous when it was concordant with the decision of the original treating interventional cardiologist (109 of 163 cases [66.9%]) compared with when it was discordant (28 of 71 cases [39.4%]; P < .001). When the heart team agreed with the original treatment decision, there was more agreement between the heart team interventional cardiologist and the original treating interventional cardiologist (138 of 163 cases [84.7%]) compared with when the heart team disagreed with the original treatment decision (14 of 71 cases [19.7%]); P < .001). Those with an original treatment of coronary artery bypass grafting, percutaneous coronary intervention, and medication therapy, 32 of 148 patients [22.3%], 32 of 71 patients [45.1%], and 6 of 15 patients [40.0%], respectively, received a different treatment recommendation from the heart team than the original treating interventional cardiologist; the difference across the 3 groups was statistically significant (P = .002). Conclusions and relevance: The heart team's recommended treatment for patients with multivessel coronary artery disease differed from that of the original treating interventional cardiologist in up to 30% of cases. This subset of cases was associated with a lower frequency of unanimous decisions within the heart team and less concordance between the interventional cardiologists; discordance was more frequent when percutaneous coronary intervention or medication therapy were considered. Further research is needed to evaluate whether heart team decisions are associated with improvements in outcomes and, if so, how to identify patients for whom the heart team approach would be beneficial
Spontaneous neck haematoma
A 66-year-old Caucasian woman presented with right-sided neck swelling and worsening pain for 5 days. There was no history of trauma, cough or excessive muscular strain. She was not on any anticoagulants or antiplatelet drugs. On initial examination, a 5Ć4 cm swelling was seen on the trapezius in the posterior triangle of the right side of the neck. The swelling was tender, firm and not mobile on palpation. A CT scan of the neck showed resolving haematoma 3 cm deep to the right trapezius muscle at the level of the hyoid bone. She was treated as an outpatient with analgesics. A repeat CT scan after 4 weeks showed complete resolution of the haematoma. A Medline literature search did not reveal any reported cases of spontaneous haematoma in the posterior triangle of the neck without any precipitating factor
Assessment of knowledge of use of electronic cigarette and its harmful effects among young adults
The practice of young adults smoking e-cigarette may have been adopted as a way of smoking cessation or just to follow a trend. Most people still remain unaware of the detrimental effects of e-cigarette. This study was carried out to assess the prevalence of the habit of smoking e-cigarette and the awareness of its harmful effects among adults aged 18ā23 years
