Objectives: This study compares the transradial versus the transfemoral approach for time to intervention for patients presenting with ST elevation myocardial infarction (STEMI)., Background: Survival following STEMI is associated with reperfusion times (door-to-balloon; D2B). For patients undergoing primary PCI for acute STEMI, potential effects of transradial approach (r-PCI) as compared with the femoral artery approach (f-PCI) on D2B times have not been extensively studied., Methods: Consecutive patients presenting with STEMI at a tertiary care medical center were enrolled in a comprehensive-Heart Alert program (HA) and included in this analysis. Time parameters measured included: door-to-ECG, ECG-to-HA activation, HA activation-to-cath lab team arrival, patient arrival in cath lab to arterial access, and arterial access-to-balloon inflation., Results: Of 240 total patients, 205 underwent successful PCI (n = 124 r-PCI; n = 116 f-PCI). No significant difference was observed in the pre-cath lab times. Mean case start times for r-PCI took significantly longer (12.5 +/- 5.4 min vs. 10.5 +/- 5.7 min, P = 0.005) due to patient preparation. Once arterial access was obtained, balloon inflation occurred faster in the r-PCI group (18.3 vs. 24.1 min; P < 0.001). Total time from patient arrival to the cardiac cath lab to PCI was reduced in the r-PCI as compared to the f-PCI group (28.4 vs. 32.7 min, P = 0.01). There was a small but statistical difference in D2B time (r-PCI 76.4 min vs. f-PCI 86.5 min P = 0.008)., Conclusions: Patients presenting with STEMI can undergo successful PCI via radial artery approach without compromise in D2B times as compared to femoral artery approach., ((c) 2009 Wiley-Liss, Inc.)

Background: It has been shown that women are at greater risk than men of not receiving screening and treatment services for coronary heart disease. The purpose of this research was to determine whether there were gender disparities in the use of percutaneous coronary interventions (PCI) in the treatment of acute myocardial infarction (AMI) in Pennsylvania in 2000 and, if so, whether outcomes were affected., Methods: Data included 10,170 patients treated with PCI and 21,181 patients medically managed in Pennsylvania hospitals. Multivariate analyses were performed using logistic regression to estimate the impact of gender on PCI. In addition, we performed retrospective matching on propensity scores to compare outcomes for women who were treated with PCI to comparable groups of women and men., Results: After controlling for age, race/ethnicity, severity at admission, location of infarct, and source of admission, women had 24% lower odds than men of receiving PCI (P<0.0001). In a propensity score-matched sample of 3023 women who received PCI and 3023 women who did not, women who received PCI were significantly less likely to die (2.3% vs. 10.4%, P<0.0001). In a second propensity score-matched sample of 3329 women and 3329 similar men who received PCI, the difference in mortality was not statistically significant (1.59% vs. 1.92%, P=0.39)., Conclusions: These results suggest that the morbidity and mortality associated with AMI in women could be reduced by increased use of PCI and that more women admitted for AMI should receive consideration for PCI.

In the United States, coronary heart disease (CHD) is the leading cause of death for women. Combined with hypertension, stroke, and other vascular conditions, one in every two women dies annually owing to a cardiovascular condition. During the past 20 years, overall death rate from CHD has declined, but the rate of decline has been lower for women compared with men. Trials and studies have demonstrated that CHD might be preventable; however, optimal treatment strategies for women are still in question. It is, therefore, essential that the medical profession continues its current efforts to focus on the development of clinical practice guidelines that critically evaluate both diagnostic and therapeutic treatment options for women with CHD.
