Background:Previous trials have found that low low-density lipoprotein-cholesterol (LDL-C) on admission was associated with increased mortality in patients with acute myocardial infarction (AMI). There are few reports, however, on the effect of low LDL-C with or without in-hospital statin treatment on short-term prognosis in AMI patients.Methods and Results:A total of 9,032 AMI patients underwent primary PCI in 68 centers in the Tokyo CCU Network Registry during 2009–2012, in whom LDL-C was measured in 6,486. We divided them into 4 groups: statin-treated/LDL-C <100 mg/dl (n=1,236), statin-treated/LDL-C ≥100 mg/dl (n=3,671), statin-naïve/LDL-C <100 mg/dl (n=662), and statin-naïve/LDL-C ≥100 mg/dl (n=917). We assessed hospital mortality within 30 days. In-hospital all-cause mortality was significantly lower in the statin-treated/LDL-C ≥100-mg/dl group (3.2%, P<0.001). On multivariate Cox regression analysis, adjusted for age, gender, hypertension, diabetes mellitus, dyslipidemia and other clinical factors, the combination of statin treatment and LDL-C ≥100 mg/dl was an independent predictor of lower in-hospital mortality (adjusted HR, 0.211; 95% CI: 0.096–0.462; P<0.001). In the LDL-C <100-mg/dl patients, statin treatment also independently reduced in-hospital mortality (adjusted HR, 0.467; 95% CI: 0.223–0.976; P=0.043). Spontaneously low LDL-C was associated with increased short-term mortality.Conclusions:Statin treatment was associated with better short-term outcome in patients with AMI, even in patients with low LDL-C.

Aortic complex rupture is one of the most critical complications associated with transcatheter aortic valve implantation (TAVI). Its incidence is rare, and its mechanism varies by case; therefore, it is difficult to identify the predictors of complex rupture. Herein, we report a clinical case series of aortic complex rupture. Within our cohort, the frequency of complex rupture was 0.8% (4/497 consecutive patients) with an in-hospital mortality of 0. Among these four patients with complex rupture, two underwent emergent thoracotomy and surgical hemostasis without a heart-lung machine and surgical aortic valve replacement, whereas the other two were conservatively managed. The case overview revealed the following similarities: all the patients were elderly, small women; balloon-expandable valves were used; the annulus area was small with heavily calcified leaflet; and aggressive treatment strategy was used (i.e., oversizing and post-dilatation). In such cases, TAVI should be performed with a careful strategy. Once aortic complex rupture occurs, damage can be minimized through cooperation with an institutional heart team and calm management.
