Background: Lipoprotein (a) (Lp(a)) is a complex circulating lipoprotein, and there is increasing evidence it is a risk factor for atherosclerotic cardiovascular disease (ASCVD). This study aimed to investigate the influence of Lp(a) serum levels on long-term outcomes after acute myocardial infarction (AMI).Methods and Results: Between January 2015 and January 2018, we enrolled 262 patients with AMI who underwent coronary angiography within 24 h of the onset of chest pain and had available Lp(a) data enabling subdivision into 2 groups: high Lp(a) (≥32 mg/dL: n=76) and low Lp(a) (<32 mg/dL: n=186). The primary endpoint was major adverse cardiac events (MACE), which was defined as a composite of cardiac death, nonfatal MI, and readmission for heart failure. Multivariate Cox regression analysis was performed to identify the predictors of MACE. The incidence of MACE was significantly higher in the high Lp(a) group than in the low Lp(a) group (32.8% vs. 19.6%, P=0.004). Multivariate analysis showed that Lp(a) ≥32 mg/dL was an independent predictor of MACE (hazard ratio 2.84, 95% confidence interval 1.25–6.60, P=0.013).Conclusions: High Lp(a) levels were associated with worse long-term outcomes after AMI, so Lp(a) may be useful for risk assessment.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice and induces cardiac dysfunction and stroke. The development of AF requires a trigger and also an electroanatomic substrate capable of both initiating and perpetuating AF. In the past decade, ectopic beats originating from the pulmonary veins (PV) have been identified as a source of paroxysmal AF. Thus, strategies that target the PV, including the PV antrum, are the cornerstone of most AF ablation procedures. Recently, alternative technologies to radiofrequency catheter ablation for paroxysmal AF such as balloon ablation modalities have been developed. The purpose of this review is to discuss cryoballoon ablation for paroxysmal AF.

Background:The Resolute Integrity coronary drug-eluting stent (DES), the next evolution of the Resolute DES, is designed with thinner stent struts and continuous sinusoidal technology to further enhance performance. This study evaluated the performance of the Resolute Integrity DES compared with the historical performance of Xience V.Methods and Results:We assessed the safety, efficacy, and deliverability of Resolute Integrity compared with the Xience DES, the prespecified historical control, in PROPEL, a large, real-world prospective, single-arm, open-label study. A total of 1,204 subjects were enrolled in PROPEL and treated with the Resolute Integrity DES at 76 sites in Japan. Lesion and procedural success rates were 100% and 99%, respectively. Patients were equally complex in the Resolute Integrity and Xience cohorts. At 1 year in the clinical-only cohort, the primary endpoint target lesion failure was 4.3% (34/800) in the Resolute Integrity cohort compared with 8.5% (97/1,142) in the Xience historical controls (P<0.001 for non-inferiority). Target vessel failure, major adverse cardiac events, target vessel myocardial infarction, and the composite cardiac death and target vessel myocardial infarction were all lower with Resolute Integrity compared with Xience, including in “high risk” patients.Conclusions:In the large, prospective, multicenter PROPEL trial, the performance of the Resolute Integrity DES was non-inferior to that of the benchmark Xience DES used as a historical comparator.

Background:Clinical use of fractional flow reserve (FFR) has been rapidly increasing, but outcomes after FFR-based coronary intervention in Japanese daily clinical practice have not been well investigated.Methods and Results:The prospective multicenter cardiovascular intervention therapeutics registry (CVIT)-DEFER enrolled consecutive patients for whom FFR measurement was clinically indicated. This study comprised 3,857 vessels in 3,272 patients. Lesions were categorized into 4 groups according to FFR result and revascularization strategy: group 1: FFR >0.8, and deferral of PCI (n=1992); group 2: FFR >0.8, then PCI (n=230); group 3: FFR ≤0.8, and deferral of PCI (n=506); and group 4: FFR ≤0.8, then PCI (n=1,129). The event rate for deferred lesions was significantly low compared with that for PCI lesions (3.5% vs. 6.6%; P<0.05). Vessel-related events occurred in 62 (3.1%), 11 (4.8%), 25 (4.9%), and 79 (7.0%) patients in groups 1, 2, 3, and 4, respectively. PCI for lesions in which FFR was >0.8 (group 2) showed no improvement in the event rate compared with a defer-strategy. On the other hand, deferred lesions with lower FFR values had a higher risk of vessel-related events.Conclusions:A FFR-based revascularization strategy in daily clinical practice was safe with regard to vessel-related events.
