Abstract Aims Fractional flow reserve (FFR) has never been investigated in patients with reduced ejection fraction and associated coronary artery disease (CAD). We evaluated the impact of FFR on the management strategies of these patients and related outcomes. Methods and results From 2002 to 2010, all consecutive patients with left ventricular ejection fraction (LVEF) ≤50% undergoing coronary angiography with ≥1 intermediate coronary stenosis [diameter stenosis (DS)% 50–70%] treated based on angiography (Angiography-guided group) or according to FFR (FFR-guided group) were screened for inclusion. In the FFR-guided group, 433 patients were matched with 866 contemporary patients of the Angiography-guided group. For outcome comparison, 617 control patients with LVEF >50% were included. After FFR, stenotic vessels per patient were significantly downgraded compared with the Angiography-guided group (1.43 ± 0.98 vs. 1.97 ± 0.84; P < 0.001). This was associated with lower revascularization rate (52% vs. 62%; P < 0.001) in the FFR-guided vs. the Angiography-guided group. All-cause death at 5 years of follow-up was significantly lower in the FFR-guided as compared with Angiography-guided group [22% vs. 31%. HR (95% CI) 0.64 (0.51–0.81); P < 0.001]. Similarly, rate of major adverse cardiovascular and cerebrovascular events (MACCE: composite of all-cause death, myocardial infarction, revascularization, and stroke) was significantly lower in the FFR-guided group [40% vs. 46% in the Angiography-guided group. HR (95% CI) 0.81 (0.67–0.97); P = 0.019]. Higher rates of death and MACCE were observed in patients with reduced LVEF compared with the control cohort. Conclusions In patients with reduced LVEF and CAD, FFR-guided revascularization was associated with lower rates of death and MACCE at 5 years as compared with the Angiography-guided strategy. This beneficial impact was observed in parallel with less coronary artery bypass grafting and more patients deferred to percutaneous coronary intervention or medical therapy.

The Impact

Introduction The impact of preserved and reduced left ventricular ejection fraction (LVEF) has been well studied in heart failure, but not in hypertension. We aimed to highlight the prevalence, clinical characteristics, comorbidities and outcomes of hospitalized hypertensives with preserved and reduced LVEF from three teaching hospitals in Nigeria. Methods: This is a retrospective study of hypertensives admitted in 2013 in three teaching hospitals in Lagos, Kano and Ogbomosho, who had echocardiography done while on admission. Medical records and echocardiography parameters of the patients were retrieved and analyzed. Results: 54 admitted hypertensive patients who had echocardiography were recruited, of which 30 (55.6%) had reduced left ventricular ejection fraction (RLVEF), defined as ejection fraction <50%; while 24 (44.4%) had preserved left ventricular ejection fraction (PLVEF). There were 37(61.5%) females and 17 (31.5%) males. Of the male patients 64.7% had RLVEF, while 35.3% had PLVEF. 19(51.4%) of females had RLVEF, while 48.6% had PLVEF. Mean age of patients with PLVEF was 58.83±12.09 vs 54.83± 18.78 of RLVEF; p-0.19. Commonest comorbidity was Heart failure (HF) followed by stroke (found among 59.3% and 27.8% of patients respectively). RLVEF was significantly commoner than PLVEF in HF patients (68.8% vs 31.3%; p- 0.019); no significant difference in stroke patients (46.7% vs 53.3%; p-0.44). Mortality occurred in 1 (1.85%) patient who had RLVEF.         Conclusion: RLVEF was more common than PLVEF among admitted hypertensive patients; they also have more comorbidities. In-hospital mortality is, however, very low in both groups.

Anthracycline Dose

Background Anthracyclines are a key chemotherapeutic agent used against hematological and solid organ malignancies. However, their benefits in cancer survival are limited by cumulative, dose‐related cardiotoxicity. The impact of anthracyclines on left ventricular ejection fraction (LVEF), in the era of modern chemotherapy regimens, remains unclear. Methods and Results Three databases (CENTRAL, MEDLINE, and SCOPUS) were systematically searched for randomized trials evaluating cardioprotective agents against placebo, in preventing cardiotoxicity. Echocardiography or magnetic resonance measured LVEF pre‐ and post‐anthracycline‐based chemotherapy was abstracted from placebo trial arms. The key terms included “anthracycline,” “cardiotoxicity” and “randomized.” A doxorubicin equivalent anthracycline dose metric was calculated to compare different anthracyclines. A random‐effects model was used to pool mean difference in LVEF after anthracycline. Meta‐regressions were calculated to identify variation sources. We included 660 patients from 19 trials. The weighted mean baseline LVEF across studies was 62.6%, and follow‐up LVEF assessment was performed at 6 months. The pooled mean decline in LVEF among placebo arms was 5.4% (95% CI, 3.5%–7.3%) with a doxorubicin equivalent anthracycline dose of 385 mg/m 2 . Meta‐regression analysis showed no significant difference in LVEF against doxorubicin equivalent anthracycline dose as continuous ( P =0.29) or against published cut‐offs for cardiotoxicity (250 mg/m 2 , P =0.21; 360 mg/m 2 , P =0.40; and 400 mg/m 2 , P =0.66). The differences in mean LVEF were not associated with sex, adjunct chemotherapy, or cancer type. Conclusions The magnitude of LVEF impairment post‐anthracycline therapy appears less than previously described with modern dosing regimens. This may improve the accuracy of power calculation for future clinical trials assessing the role of cardioprotective therapy.

Background: Length of stay is an important quality metric and outcome measure in the management of hospitalized patients. We evaluated the association of diabetes in patients admitted for Non-ST Elevation myocardial infarction (NSTEMI) on their length of stay. Hypothesis: the impact of diabetes on length of stay in patients admitted for STEMI Methods: Our study population included patients admitted for NSTEMI in a single center between 08/01/2016 and 09/30/2012. Diabetes (DM) was defined by a documented diagnosis or use of diabetic medication. A higher length of stay (LOS) was defined as spending more than 5 days in the hospital. Results: A total of 720 patients were included in this analysis. The mean age was 66 ± 0.6 years, 50% (n-269) were diabetics, 59% had left ventricular ejection fraction (EF) < 50% and the median LOS was 5 days. A higher number of diabetic patients had LOS> 5days (55%). In an unadjusted logistic regression, diabetics had increased odds of higher LOS, odd ratio (OR) 1.54 ( CI 1.10-2.16 ), p=0.012. After adjusting for confounding variables, the relationship remained significant. When stratified by left ventricular systolic function on admission, the impact of diabetes on length of stay only remained significant in patients with EF less than 50%. See Table 1. Conclusion: The presence of diabetes was significantly associated LOS in NSTEMI, especially for patients admitted with a reduced left ventricular ejection fraction. This study emphases the impact of diabetes on health comes in cardiovascular disease.
