Gender Differences Among Very Young Patients With Acute Coronary Syndrome: Long-Term Follow-Up of the STAMINA Study.

The rate of hospitalization for acute coronary syndrome (ACS) among young patients is increasing. Healthcare disparities remain unsolved among female patients. We explored gender differences regarding risk factors, clinical presentation, in-hospital treatment, and long-term outcomes among ACS patients. A total of 445 patients with very early ACS (men ≤ 35 years and women ≤ 40 years of age) were followed for a median of 5 years. Primary clinical endpoint was the composite of cardiac death, non-fatal myocardial infarction, stroke, and coronary revascularization. Women accounted for 16% of cases. Smoking was the most prevalent risk factor, 56% and 60% of the females and males, respectively, continued to smoke after ACS. Chest pain was typical in 85% and 83% of the female and male patients, respectively. In-hospital treatment (pharmacological and reperfusion) as well as the composite clinical endpoint during follow-up did not differ between female and male patients. Lipid-lowering therapy was suboptimal in both genders, and persistence of smoking was the sole predictor for the composite clinical endpoint (hazard ratio: 2.30 [95% CI: 1.26-4.20]; P = .007). In conclusion, in-hospital treatment was similar between male and female patients. However, the majority of them continued smoking, and this was an independent predictor for future adverse outcomes.

Outcomes from treatment of metastatic renal-cell carcinoma following failure of first-line anti-VEGF/VEGFR therapy: real-life evidence on the change of the treatment paradigm.

Recently approved agents for post-vascular endothelial growth factor/post-vascular endothelial growth factor receptor (VEGF/VEGFR) inhibitors treatment of metastatic renal-cell carcinomas (mRCC), such as axitinib, nivolumab, and cabozantinib were shown to improve prognosis and substituted everolimus in this setting. We studied practice patterns, efficacy, and tolerability of these agents in a real-world series of Greek patients. We included patients with mRCC who received everolimus, axitinib, or nivolumab after progression on first-line anti-VEGF/VEGFRs therapy. Patients were stratified into three groups. Group A received nivolumab with or without cabozantinib at some point in their disease. Group B received axitinib but without nivolumab or cabozantinib. Group C received only everolimus among the four approved agents. Overall, 131 patients were included in the analysis. Everolimus and nivolumab were mainly used in the second line, while axitinib and cabozantinib were mostly used in the third and fourth lines. Median overall survival (OS) from first-line initiation was 8.7 [95% confidence interval (CI), 4-not reached], 3.6 (95% CI, 2-6), and 2.1 years (95% CI, 1.4-2.6) for Group A, B, and C, respectively ( P < 0.001). Median OS from the initiation of second-line therapy was 3.5, 2.7, and 1.3 years, respectively ( P < 0.001). There was no impact of first-line agent or treatment timing on survival. International Metastatic Renal Cell Carcinoma Database Consortium risk stratification was associated with OS. Toxicities observed were within expected frequencies. Grade ≥3 events were rare. Adoption of modern standards in everyday treatment of mRCC results in prolongation of survival. Real-world datasets are the new landmarks of survival for future research.

Effect of High (200 µg/kg per Minute) Adenosine Dose Infusion on Fractional Flow Reserve Variability.

BACKGROUND: Variations in distal coronary pressure (Pd)/aortic pressure (Pa) ratio during steady-state hyperemia with standard (140 µg/kg per minute) adenosine dose may hamper accurate fractional flow reserve assessment. This study investigated to what extent an increased adenosine dose can overcome Pd/Pa variation. METHODS AND RESULTS: In a prospective, single-arm study, out of 95 prospectively screened patients, 38 (40.0%) exhibited significant (≥0.05 difference of max Pd/Pa minus min Pd/Pa) variations in Pd/Pa from 15 s post Pd/Pa dip and until the end of a 3-minute adenosine (140 µg/kg per minute) infusion. Thirty patients agreed to participate in a post 5-minute repeat fractional flow reserve assessment using 200 µg/kg per minute 3-minute adenosine infusion. The study's co-primary end point of Pd/Pa coefficient of dispersion was lower for the high versus standard adenosine dose: 1.31 (1.13-2.72) versus 2.76 (2.38-5.60), P=0.002. The study's co-primary end point of ΔPd/Pa was also lower for the high versus standard adenosine dose: 0.065 (0.038-0.10) versus 0.08 (0.06-0.11), P=0.002. This difference was mainly driven by the lowering effect of the high adenosine dose on the maximum Pd/Pa compared to the standard dose: 0.84 (0.81-0.93) versus 0.90 (0.83-0.95), P=0.007, while minimum Pd/Pa remained unaffected. High adenosine dose was adequately tolerated by all patients, without requiring infusion discontinuation in any case. CONCLUSIONS: Pd/Pa variability is frequently observed during standard adenosine infusion and is significantly decreased following a high (200 µg/kg per minute) adenosine dose. This is achieved without a significant difference in the minimum Pd/Pa. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov. Unique identifier: NCT02350439.
