Aim: We investigated the relationship between small dense low-density cholesterol (sdLDL-C) and risk of major adverse cardiovascular events (MACE) in patients treated with high- or low-dose statin therapy.Methods: This was a prospective case-cohort study within the Randomized Evaluation of Aggressive or Moderate Lipid-Lowering Therapy with Pitavastatin in Coronary Artery Disease (REAL-CAD) study, a randomized trial of high- or low-dose (4 or 1 mg/d pitavastatin, respectively) statin therapy, in patients with stable coronary artery disease (CAD). Serum sdLDL-C was determined using an automated homogenous assay at baseline (randomization after a rule-in period, >1 month with 1 mg/d pitavastatin) and 6 months after randomization, in 497 MACE cases, and 1543 participants randomly selected from the REAL-CAD study population.Results: High-dose pitavastatin reduced sdLDL-C by 20% than low-dose pitavastatin (p for interaction <0.001). Among patients receiving low-dose pitavastatin, baseline sdLDL-C demonstrated higher MACE risk independent of LDL-C (hazard ratio [95% confidence interval], 4th versus 1st quartile, 1.67 [1.04–2.68]; p for trend=0.034). High-dose (versus low-dose) pitavastatin reduced MACE risk by 46% in patients in the highest baseline sdLDL-C quartile (>34.3 mg/dL; 0.54 [0.36–0.81]; p=0.003), but increased relative risk by 40% in patients with 1st quartile (≤ 19.5 mg/dL; 1.40 [0.94–2.09]; p=0.099) and did not alter risk in those in 2nd and 3rd quartiles (p for interaction=0.002).Conclusions: These findings associate sdLDL-C and cardiovascular risk, independent of LDL-C, in statin-treated CAD patients. Notably, high-dose statin therapy reduces this risk in those with the highest baseline sdLDL-C.

Background: In atrial fibrillation (AF) patients, the effect of direct oral anticoagulant (DOACs) therapy on the incidence of left atrial appendage thrombus (LAT) remains poorly investigated. This study examined the prevalence and risk factors of LAT in AF patients on DOACs undergoing catheter ablation, and sought an anticoagulation strategy for LAT. Methods and Results: In 407 AF patients on DOACs, transesophageal echocardiography (TEE) was performed 1 day before ablation. If patients had LAT, initial DOACs were switched to dabigatran (300 mg) or warfarin based on their renal function; TEE was repeated after treatment for ≥4 weeks. LAT was detected in 18 patients (4.4%). The prevalence of persistent AF and low-dose treatment/inappropriate dose reduction of DOACs, CHADS2/CHA2DS2-VASc scores, serum N-terminal pro-brain natriuretic peptide levels, and LA dimension/LA volume index significantly increased in patients with LAT vs. those without LAT. AF rhythm on TEE and spontaneous echo contrast also increased in patients with LAT; LA appendage flow velocity decreased. In the multivariate analysis, persistent AF and inappropriately reduced DOAC dose were risk factors for LAT. On repeat TEE, LAT had disappeared in 13 of 16 patients treated with dabigatran and in 2 of 2 patients treated with warfarin. Conclusions: DOACs still carry a finite risk of LAT in AF patients. Inappropriately reduced DOAC dose should be avoided to minimize the thromboembolic risk. Regular-dose dabigatran may have therapeutic efficacy against LAT.

Background: Remote monitoring (RM) technology has emerged as a potentially efficient method to manage patients with implantable cardioverter defibrillators (ICDs) or cardiac resynchronization therapy defibrillators (CRT-Ds). This study evaluated the reliability of daily RM in forecasting the need for regular in-hospital follow-ups (RFUs). Methods and Results: Two hundred and fifteen patients implanted with Biotronik Lumax devices (142 ICDs, 73 CRT-Ds) were enrolled. RFU was performed at 3, 6, 9, and 12 months after implantation. Immediately before an RFU, the physician forecasted the need for RFU based on RM data (pre-RFU assessment). A completed RFU session was classified as necessary if an action was undertaken potentially influencing patient safety, device therapy, or medication therapy (post-RFU assessment). Overall, 663 pairs of pre- and post-RFU assessments were compared. The number of pre-RFU assessments failing to predict the need for RFU was 38 (5.7%), fulfilling the study hypothesis of 5.0±4.0% (P<0.002; 95% confidence interval: 4.1–7.8%). Judged by an independent committee, the rate of false pre-RFU forecasts with high clinical relevance was 2 (0.3%). RM correctly forecasted non-necessity of 498 scheduled RFUs (75.1%). Patient acceptance of RM was evaluated using a targeted questionnaire. Of 182 interviewed patients, 172 (94.5%) felt security and comfort. Conclusions: RM-based forecasts appear sufficiently accurate to safely individualize RFU. Most patients have a positive attitude towards RM.

Background: Target anticoagulation levels for warfarin in Japanese patients with non-valvular atrial fibrillation (NVAF) are unclear. Methods and Results: Of 7,527 patients with NVAF, 1,002 did not receive warfarin (non-warfarin group), and the remaining patients receiving warfarin were divided into 5 groups based on their baseline international normalized ratio (INR) of prothrombin time (≤1.59, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0). Patients were followed-up prospectively for 2 years. Primary endpoints were thromboembolic events (cerebral infarction, transient ischemic attack, and systemic embolism), and major hemorrhage requiring hospital admission. During the follow-up period, thromboembolic events occurred in 3.0% of non-warfarin group, but at lower frequencies in the warfarin groups (2.0, 1.3, 1.5, 0.6, and 1.8%/2 years for INR values of ≤1.59, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0, respectively; P=0.0059). Major hemorrhage occurred more frequently in warfarin groups (1.5, 1.8, 2.4, 3.3, and 4.1% for INR values ≤1.59, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0, respectively; P=0.0041) than in non-warfarin group (0.8%/2 years). These trends were maintained when the analyses were confined to patients aged ≥70 years. Conclusions: An INR of 1.6–2.6 is safe and effective at preventing thromboembolic events in patients with NVAF, particularly patients aged ≥70 years. An INR of 2.6–2.99 is also effective, but associated with a slightly increased risk in major hemorrhage. (UMIN Clinical Trials Registry UMIN000001569)
