RESUMEN

INTRODUCTION: This prospective pharmacodynamic (PD) study assessed the effect of the sodium-glucose co-transporter-2 inhibitor (SGLT2i), dapagliflozin, on platelet reactivity. METHODS: Patients with stable coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM) (n = 27) who were on maintenance dual antiplatelet therapy (DAPT) of aspirin 81 mg daily, and clopidogrel 75 mg daily were recruited. Platelet function was evaluated with the VerifyNow™ P2Y12 assay (Werfen, Bedford, MA, USA) and assessed prior to initiation of and after 10 days of treatment with dapagliflozin 10 mg once-daily dose regimen. Results were compared with a paired t test. RESULTS: Treatment with dapagliflozin significantly decreased P2Y12 reaction units (PRU) by 20%, (95% confidence interval (CI) 8.5-32.6%, p value 0.002). The mean difference in PRU was 36.70 (95% CI 16.66-56.75). No patients experienced any serious adverse events (SAEs). CONCLUSIONS: Significantly diminished platelet reactivity was observed on dapagliflozin as compared to without dapagliflozin. This dedicated pharmacodynamic study could be potentially informative and applicable for Trinidadian stable CAD patients with T2DM on DAPT. Further studies are required to confirm these exploratory findings. CLINICAL TRIAL REGISTRATION: EDGE ClinicalTrials.gov number NCT04400760.

RESUMEN

The Africanized honey bee commonly referred to as the "killer bee," is a hybrid of the East African lowland honey bee with various European honey bees. These bees tend to be more hostile as compared to other bee species. Their stings may have devastating clinical sequelae, including cardiovascular, cerebrovascular events, and fatalities. We report the first-in-Caribbean case of a middle-aged woman who experienced stress-related, Takotsubo cardiomyopathy (also known as stress-related cardiomyopathy [SRC]) after being afflicted with innumerable Africanized honey bee stings. Key clinical message: The clinician should be cognizant of Takotsubo's cardiomyopathy as a potential sequela of Hymenoptera envenomation and anaphylaxis.

RESUMEN

Ventricular noncompaction is a rare, heterogeneous cardiomyopathy characterized by marked trabeculations and deep intertrabecular spaces with clinical sequelae of heart failure, arrhythmias, and cardioembolic events. In this article, we describe a patient with isolated right ventricular noncompaction who presented with submassive pulmonary embolism, which was managed with long-term direct oral anticoagulation.

RESUMEN

INTRODUCTION: This prospective pharmacodynamic (PD) study aimed to assess the effect of the sodium-glucose cotransporter 2 inhibitor (SGLT2i) empagliflozin on platelet reactivity. METHODS: Patients with stable coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM) (n = 20) who were actively treated with dual antiplatelet therapy (DAPT) of aspirin 81 mg daily and clopidogrel 75 mg daily were recruited. Platelet function was measured with the VerifyNow™ P2Y12 assay (Instrumentation Laboratory, Massachusetts, USA) and assessed before the initiation of and after 10 days of treatment with empagliflozin 25 mg once daily maintenance dose regimen. Results were compared with a paired t test. RESULTS: The mean P2Y12 reaction units (PRU) on empagliflozin was significantly less than without empagliflozin at baseline (187.35, 95% confidence interval (CI) 155.38-219.32 vs. 217.25, CI 180.60-253.90; p < 0.030). The mean difference in PRU was 29.90 (95% CI 3.17-56.63). No patients experienced any serious adverse events (SAEs). CONCLUSIONS: Significantly attenuated platelet reactivity was observed on empagliflozin as compared to without empagliflozin. This dedicated pharmacodynamic study could be clinically pertinent for Trinidadian patients with stable CAD and T2DM on DAPT. Further studies are required to confirm these exploratory findings.

RESUMEN

INTRODUCTION: This prospective, pharmacodynamic study aimed to explore the potential applicability of a low-dose ticagrelor regimen in a heterogeneous Trinidadian subpopulation. METHODS: Patients with stable coronary artery disease (n = 25) who were actively treated with dual antiplatelet therapy of aspirin 81 mg daily and clopidogrel 75 mg daily were recruited. Platelet function was measured with the VerifyNow P2Y12 assay (Accriva Diagnostics, San Diego, CA, USA) and assessed before initiation of and after 14 days of treatment with a low-dose ticagrelor 45 mg twice daily maintenance dose regimen. Results were compared with a paired t test. RESULTS: The mean P2Y12 reaction units (PRU) score on ticagrelor was significantly less compared to that of clopidogrel (50.4, 95% confidence interval (CI) 29-73.9; vs. 149.6, 95% CI 129.4-169.9; p value < 0.001). Of the patients, 4% experienced Medical Research Council class 1 dyspnea, and Bleeding Academic Research Consortium class 1 bleeding on the ticagrelor regimen (one patient each). CONCLUSIONS: Significantly attenuated platelet reactivity was seen on the low ticagrelor maintenance dose as compared to clopidogrel. This dedicated pharmacodynamic study could be applicable and informative for Trinidadian stable coronary artery disease patients. Further studies are required to confirm these exploratory findings.(Funded by the University of the West Indies, St. Augustine). TRIAL REGISTRATION: ClinicalTrials.gov number NCT04206176.
