OnBehalf PHASE-MX Background/Introduction: Early routine angiography with subsequent Percutaneous Coronary Intervention (PCI) (if needed) after fibrinolysis reduced the rates of reinfarction and recurrent ischemia compared with a ‘watchful waiting’ strategy. A crucial issue is the optimal time delay between successful lysis and PCI, there is a wide variation in delay in trials from a median of 1.3 h to 17h (CAPITAL AMI, GRACIA-1 and STREAM trials). At present a time window of 2-24h after successful lysis is recommended. Purpose   To analyze the incidence of major cardiovascular outcomes in patients with ST-segment elevation myocardial infarction (STEMI) according to the timing of PCI after lysis (pharmacoinvasive strategy, less/more than 24h). Methods A retrospective analysis of the PHASE-MX study (ClinicalTrials.gov Identifier: NCT03974581) including patients with STEMI whom underwent pharmacoinvasive strategy during the first 12h since symptom onset. Patients were further stratified according to the time from the use of fibrinolysis to sheat insertion (<24h or >24h) in the completion of pharmacoinvasive strategy. The primary composite endpoint included the occurrence of cardiovascular death, cardiogenic shock, recurrent myocardial infarction or congestive heart failure at 30 days of follow-up. Results A total of 171 patients were included, of whom 34 underwent PCI after fibrinolysis in less than 24 hours and 137 underwent PCI in more than 24 hours (95% CI 24-120h). Mostly were male (86.4%), mean age was 56.4 ±12.1 years. The primary composite endpoint occurred in 2 patients (5.8%) in PCI < 24 hours and 12 patients (8.6%) in PCI >24 hours (p 0.58). PCI in <24h after lysis was not associated with a reduced risk of the primary endpoint (HR 0.66 95%CI: 0.14-2.97). Conclusion In patients with successful fibrinolysis undergoing to PCI the first 24 h was not associated with a reduced risk of cardiovascular death, cardiogenic shock, recurrent MI or congestive heart failure at 30 days comparing with PCI after 24 h.

Background: Thiazolidinediones (TZD) have been shown to decrease intimal hyperplasia by intravascular ultrasound after coronary stenting. However, a recent meta-analysis showed increased MI and suggested increased CV deaths with TZD use. We examined the impact of TZD use on the 1-year clinical outcomes of diabetic patients undergoing percutaneous coronary interventions. Methods: From 2000 through 2003, 598 diabetic patients underwent percutaneous coronary intervention at Emory University. Medication profiles were available for all patients who were divided into two groups: those that had a TZD as part of their diabetes regimen and those that did not. We compared the baseline clinical characteristics, angiographic characteristics, and 1 year rate of a composite endpoint of death, myocardial infarction, and revascularization between the two groups. Results: There was no difference between the two groups with regards to age, sex, baseline medical conditions, medication regimens, and overall glycemic control at the time of percutaneous coronary intervention. The lesions in both groups were of similar length, diameter, and characteristics. At 1 year the composite of death, non-fatal myocardial infarction (MI), and revascularization was not statistically different in the diabetics taking TZDs compared to those not taking TZDs (28.5% vs. 23.2%, p=0.15). There were also no differences in the rates of death and non-fatal MI. There was however a statistically significant increase in the rate of revascularization in diabetics taking TZDs compared to those not taking TZDs (25.4% vs. 17.3%, p=0.02). Conclusion: Diabetic patients undergoing coronary stenting who were on TZDs had a statistically significant increased rate of revascularization. However, there was a similar rate of the combined endpoint of death, non-fatal MI, and revascularization in all diabetic patients irrespective of TZD usages.

BACKGROUND: Few studies have examined the relationship between vitamin D levels and incident cardiovascular events in large well-characterized type 2 diabetes cohorts. METHODS: We performed prospective analyses to determine associations between vitamin D status and vascular endpoints among 936 Veterans Affairs Diabetes Trial (VADT) participants (mean age 59.7 years; 96.7% male; 40.4% minority). 25 (OH)-vitamin D was measured a median of two years after entry into the VADT study and participants were subsequently followed an average of 3.7 years for outcomes. Cox proportional hazard models were used to calculate hazard ratios (HRs) for macrovascular endpoints in relation to vitamin D quartile. The primary composite endpoint included documented myocardial infarction; stroke; death from cardiovascular causes; new or worsening congestive heart failure; surgical intervention for cardiac, cerebrovascular, or peripheral vascular disease; inoperable coronary artery disease; and amputation for ischemic gangrene. RESULTS: On average VADT participants had high cardiovascular risk at entry into the study: 65.3% of the patients recruited were obese, 38.5% had previously had a vascular event, 78.7% had hypertension and 59.5% were using statins. During follow-up, 17.2%, 5.0%, 5.9%, 2.4% and 6.6% of participants had a primary composite endpoint, myocardial infarction, chronic heart failure, cardiovascular death or all-cause death, respectively. After adjusting for age, minority status, treatment arm and history of prior event, individuals in the lowest quartile of vitamin D (i.e., 1 to 15.9 ng/ml) were at similar risk of the primary composite endpoint [HR=1.26 (95% CI: 0.81, 1.96)], myocardial infarction [HR=1.13 (95% CI: 0.53, 2.42)], congestive heart failure [HR=1.44 (95% CI: 0.67, 3.06)], cardiovascular death [HR=0.86 (95% CI: 0.28, 2.63)], and death from any cause [HR=1.04 (95% CI: 0.53, 2.04)] as individuals in the highest quartile of vitamin D (i.e., 29.9 to 77.2 ng/ml). CONCLUSIONS: These data indicate that vitamin D status had no significant impact on the incidence of macrovascular events in a cohort of high-risk veterans with type 2 diabetes mellitus in which traditional risk factors were managed according to current treatment guidelines.

Background: Among patients receiving percutaneous coronary intervention (PCI), the role of a genotype-guided approach for antiplatelet therapy compared with usual care is unclear. We conducted a Bayesian analysis of the entire TAILOR-PCI (Tailored Antiplatelet Initiation to Lessen Outcomes Due to Decreased Clopidogrel Response After Percutaneous Coronary Intervention) randomized clinical trial population to evaluate the effect of the genotype-guided antiplatelet therapy post-PCI compared with the usual care on the risk of major adverse cardiovascular events (MACE). Methods: The primary outcome for our study was the composite of MACE (myocardial infarction, stroke, and cardiovascular death). Secondary outcomes included cardiovascular death, stroke, myocardial infarction, stent thrombosis, and major/minor bleeding. Bayesian modeling was used to estimate the probability of clinical benefit of genotype-guided therapy using (1) noninformative priors (ie, analyzing the TAILOR-PCI trial) and (2) informative priors derived from the ADAPT, POPular Genetics, IAC-PCI, and PHARMCLO trials (ie, analyzing TAILOR-PCI trial in the context of prior evidence). Risk ratio (RR: ratio of cumulative outcome incidence between genotype-guided and conventional therapy group) and 95% credible interval (CrI) were estimated for the study outcomes, and probability estimates for RR <1 were computed. Results: Using noninformative priors, in TAILOR-PCI the RR for MACE was 0.78 (95% CrI, 0.55–1.07) in genotype-guided therapy after PCI, and the probability of RR <1 was 94%. Using noninformative priors, the probability of RR <1 for cardiovascular death (RR, 0.95 [95% CrI, 0.52–1.74]), stroke (RR, 0.68 [95% CrI, 0.44–1.06]), myocardial infarction (RR, 0.84 [95% CrI, 0.37–1.89]), stent thrombosis (RR, 0.75 [95% CrI, 0.37–1.45]), and major or minor bleeding (RR, 1.22 [95% CrI, 0.84–1.77]) were 57%, 96%, 67%, 94%, and 15%, respectively. Using informative priors, the posterior probability of RR <1 for MACE, from genotype-guided therapy, was 99% (RR, 0.69 [95% CrI, 0.57–0.84]). Using informative priors, the posterior probability of RR <1 for cardiovascular death (RR, 0.86 [95% CrI, 0.61–1.19]), stroke (RR, 0.69 [95% CrI, 0.48–0.99]), myocardial infarction (RR:0.56 [95% CrI, 0.40–0.78]), stent thrombosis (RR, 0.59 [95% CrI, 0.38–0.94]), and major or minor bleeding (RR, 0.84 [95% CrI, 0.70–0.99]) were 81%, 99%, 99%, 99%, and 99%, respectively. Conclusions: Bayesian analysis of the TAILOR-PCI trial provides clinically meaningful data on the posterior probability of reducing MACE using genotype-guided P2Y 12 inhibitor therapy after PCI.
