RESUMEN

BACKGROUND: Women who have coronary artery disease (CAD) often present with atypical symptoms that may lead to misdiagnosis. We assessed strain, systolic strain rate and left ventricular dyssynchrony with 2- dimensional- speckle tracking echocardiography to evaluate its use as a non-invasive method for detecting CAD in women with normal ejection fraction compared with healthy women controls with a normal angiogram. METHODS: We included 35 women with CAD confirmed by coronary angiography and a positive exercise stress echocardiography and 35 women in a control group with a low pretest probability of CAD, normal angiogram and a normal stress echocardiography with normal EF. RESULTS: Statistically significant 2D-STE findings for the CAD vs control groups were as follows for the mean of: global circumferential strain (CS) (-19.4% vs -22.4%, P = .02); global radial S (49% vs 34%, P = .03); global radial SR (2.4 s-1 vs 1.9 s-1, P = .05); global longitudinal LV S (GLS) (-14.3% vs -17.2%, P < .001). For mechanical dyssynchrony, SD of the GLS time-to-peak (TTP) was computed (99 vs 33 ms, P < .001). The receiver operating characteristic and area under the curve (AUC) were calculated. A cutoff value of 45 ms for 1 SD of the longitudinal S TTP had 97% sensitivity and 89% specificity (AUC, 0.96). GLS cutoff value of -15.87% had 71% sensitivity and 74% specificity; AUC, 0.74 in differentiating CAD and control groups. The combined GLS, CS, and SD of the longitudinal S TTP had an AUC of 0.96 (sensitivity 97%, specificity 86%). Interclass correlations of the GLS segment and GLS TTP measurements were 0.49 (95% CI, 0.227-0.868) and 0.74 (95% CI, 0.277-0.926), respectively. CONCLUSION: In women with a normal echocardiogram and LVEF, CAD can be identified by dyssynchrony and abnormal strain values, as evidenced by 2D-STE.

RESUMEN

PURPOSE: Prostate brachytherapy is an increasingly used treatment option for low- to intermediate-risk prostate cancer (PCa). However, patients with preexisting lower urinary tract symptoms (LUTS) and PCa, who would otherwise be good brachytherapy candidates, are often contraindicated because of the risk of postoperative urinary morbidity. We report our clinical experience with limited transurethral resection of the prostate (LTURP) and/or transurethral incision of the prostate (TUIP) months before brachytherapy to treat patients with LUTS and low- to intermediate-risk PCa. METHODS AND MATERIALS: Of 258 men undergoing prostate brachytherapy at our institution between 1998 and 2011, 42 were treated with planned LTURP and/or TUIP well before (mean, 5.7 months) seed implantation. Transurethral surgery was considered before brachytherapy for patients who at presentation required α-blocker therapy for LUTS, had an International Prostate Symptom Score greater than 14 off α-blockers, or had an elevated postvoid residual (>100 mL). Patients only proceeded to brachytherapy once LUTS resolved. RESULTS: All 42 patients in our series underwent TUIP (25), LTURP (7), or TUIP/LTURP (10) with mean 5.7 months before prostate brachytherapy for low- or intermediate-risk PCa. Mean International Prostate Symptom Score, peak flow rate, and postvoid residual significantly improved after transurethral surgery, and improvement persisted at the latest followup. No patient developed retention, urethral necrosis, or urinary incontinence after transurethral surgery or brachytherapy (median followup, 39 months and range, 1-121). CONCLUSIONS: Planned LTURP and/or TUIP more than 4 months before brachytherapy is a safe and effective treatment strategy for men with LUTS and low- to intermediate-risk PCa.
