Background: Rupture of unstable coronary atherosclerotic plaque leads to acute ST-segment elevation myocardial infarction (STEMI). Dual anti-platelet therapy is one of the main treatments, and the combination of Aspirin and Clopidogrel is recognized as the standard oral regimen in most cases. Ticagrelor is a new generation of P2Y12 receptor inhibitors. We aimed to compare the effect of Ticagrelor and Clopidogrel in the treatment of patients post-STEMI.
Methods: This study investigated Pub Med, Scopus, Google Scholar Web of Science, and Embase Cochrane Library clinical trials.gov databases. Heterogeneity between studies was assessed using the I2 index and the Q statistic. The random effects model was used to combine studies and the Funnel plot and Egger's test were used to assess the publication bias.
Results: Eleven studies were included in this meta-analysis. 5274 patients in the Ticagrelor and 5,295 patients in the Clopidogrel groups were examined. The mean age of the patients was 58.84 years (2.70) and 59.92 years (3.19) in the Ticagrelor and Clopidogrel groups, respectively. Based on the results of the meta-analysis, compared to Clopidogrel, Ticagrelor had decreased the outcomes of mortality, recurrent myocardial infarction, stroke, and Major Adverse Cardiovascular Events (MACE). However, the post-myocardial infarction bleeding according to Bleeding Academic Research Consortium (BARC) criteria and reperfusion state regarding thrombolysis in myocardial infarction (TIMI) Flow Grading system showed no differences in both groups. However, these effects were not statistically significant.
Conclusions: Ticagrelor decreased the chance of mortality, re-infarction, stroke, and MACE in post-STEMI patients compared to clopidogrel. But there was no difference in the chance of major bleedings (BARC ≥ 3) and improvement in TIMI grade flow between these two drugs. However, none of these findings were statistically significant, and more studies are needed to reach definitive results.

Unveiling the Longitudinal Journey: 3-Year Follow-up of Women with MINOCA and INOCA in a Specialized Heart Centre.
CJC Open
December 2024
University of British Columbia, Vancouver, British Columbia, Canada.
Background: Myocardial infarction with no obstructive coronary arteries (MINOCA), and ischemia with no obstructive coronary arteries (INOCA), are female-predominant conditions; clinical trials are lacking to guide medical management for the common underlying vasomotor etiologies. Data on long-term outcomes of (M)INOCA patients following attendance at a women's heart centre (WHC) are lacking.
Methods: Women diagnosed with MINOCA (n = 51) or INOCA (n = 112) were prospectively followed for 3 years at the Leslie Diamond WHC (LDWHC) in Vancouver.
Thrombus on Mitral Annular Calcification: A Systematic Review of Management and Outcomes.
CJC Open

Division of Cardiology, Toronto General Hospital, University of Toronto, Toronto, Ontario, Canada.
Background: Mitral annular calcification (MAC) is a common chronic degenerative process of the mitral valve. Thrombus formation on MAC is a rare complication that likely contributes to the increased risk of thromboembolic events. Outcomes and management strategies for this condition are unknown.

Purpose: In trans people undergoing feminizing hormone therapy, optimal estradiol concentrations are unclear, and anecdotally, some individuals desire supraphysiologic estradiol concentrations. We aimed to assess associations between estradiol concentration and psychological distress, well-being, and dysphoria. Second, we aimed to explore relationships between estradiol concentration and the risk of medical conditions potentially associated with estradiol therapy.

The patient an 85-year-old female resided in a care facility where she maintained an independent daily activity level. She was discovered hunched over a table in her room, displaying reduced responsiveness and prompting an emergency call. Initially, her blood pressure was within 60 mmHg, and she was transported by ambulance to our hospital.

Background Rapid treatment of ST-elevation myocardial infarction (STEMI) patients with primary percutaneous coronary intervention (PCI) significantly reduces morbidity and mortality rates. Recent studies emphasize the importance of reducing total ischemic time, making first-medical-contact-to-balloon (FMCTB) time a key performance indicator. To improve FMCTB times in patients brought to the Emergency Department (ED) by Emergency Medical Services (EMS), we implemented a "Direct to Lab" (DTL) workflow during the following conditions: weekday daytime hours, when the lab is fully staffed, and for hemodynamically stable STEMI patients presenting via EMS.
