Article Synopsis
  • The study investigates the effects of resting heart rate (RHR) on patients with heart failure who received implantable cardioverter-defibrillators (ICDs) or cardiac resynchronization therapy-defibrillators (CRT-Ds), specifically examining RHRs above and below 70 bpm.
  • A total of 1589 patients were analyzed, and results showed that one-year all-cause mortality and major cardiovascular events were similar between those with RHR ≤ 70 bpm and > 70 bpm.
  • However, patients with RHR > 70 bpm had higher rates of all-cause hospital admissions, mainly due to non-cardiovascular events, indicating potential increased risks associated with a higher RHR.

Background: Gender-specific outcomes after percutaneous coronary interventions were studied by a number of research groups with different endpoints and cohorts of different ethnic extractions. The purpose of this report is to use propensity score matching to determine gender-specific differences in clinical outcomes after percutaneous coronary interventions with polymer-free sirolimus-coated stents.

Materials And Methods: The basis for this post hoc analysis was two large all-comers studies with prospectively enrolled patients from Europe and Asia.

Article Synopsis
  • The study evaluated the safety and effectiveness of ultrathin strut polymer-free sirolimus-eluting stents (PF-SES) in a diverse patient population undergoing percutaneous coronary interventions (PCI).
  • A total of 7243 patients were included, showing a low target lesion revascularization (TLR) rate of 2.2% and a stent thrombosis rate of 0.7% over 9-12 months of follow-up.
  • The results indicate that PF-SES are safe and effective, with particularly high procedural success rates in challenging cases like in-stent restenosis and isolated left main coronary artery disease.

Article Synopsis
  • The study aimed to evaluate regional and ethnic differences in patients treated with polymer-free sirolimus-eluting stents (PF-SES) across Asia and Europe.
  • It combined data from two observational studies, analyzing 7243 patients and focusing on target lesion revascularization (TLR) rates and major cardiovascular events (MACE) over 9-12 months.
  • Results showed low TLR (2.2%) and MACE (4.4%) rates across regions, with notably longer dual antiplatelet therapy (DAPT) in Asia compared to Europe, indicating that longer DAPT may lead to even lower clinical event rates.

Background: Patients with non-small cell lung cancer (NSCLC) and a prior or synchronous second malignancy are generally excluded from clinical trials. Therefore, little is known on prevalence and prognosis of these patients.

Methods: 1252 patients diagnosed with NSCLC in our center from 2006 to 2017 were studied.

Objective: The objective of this study was to compare the safety and efficacy of a polymer-free sirolimus coated, ultrathin strut drug eluting stent (PF-SES) to its uncoated bare-metal stent (BMS) platform of identical stent architecture.

Background: Recently published randomized trials comparing BMS to DES with a focus on shortened dual-antiplatelet therapy reported incidences of stent thrombosis (ST) and bleeding complications (LEADERS FREE) in favor of drug eluting stents (DES).

Methods: Data of previously published large-sale, international, single-armed, multicenter, observational studies of ultra-thin PF-SES, and BMS were propensity score (PS) matched for selected lesion morphological and cardiovascular risk factors to compare target lesion revascularization (TLR), myocardial infarction, cardiac death, major adverse cardiac events (MACE), bleeding complications and ST rates.

Objective: The objective of this study was to assess the safety and efficacy of a polymer-free sirolimus coated, ultrathin strut drug-eluting stent (PF-SES) in an unselected patient population with a focus on acute coronary syndrome (ACS). Furthermore, stable coronary artery disease (CAD) with short (≤6 months) versus long (>6 months) dual antiplatelet therapy (DAPT) were also studied.

Methods: Patients who received PF-SES were investigated in an unselected large-scale international, single-armed, multicenter, 'all comers' observational study.

Background: Percutaneous coronary interventions (PCI) in coronary artery disease (CAD) with very small vessel diameters remains controversial and challenging. These lesions are usually more diffuse, calcified and tortuous. The usage of thin strut bare metal stents (BMS) with excellent crossing profiles in a very small caliber coronary lesions has increased the likelihood of procedural success.

Objectives: This observational study assessed the 9-month clinical outcomes in an « all comers » population with a focus on patients with atrial fibrillation (AF) after thin strut bare metal stenting.

Background: Drug eluting stent (DES) implantation is the treatment of choice for coronary artery disease (CAD) leaving only marginal indications for the use of bare metal stents (BMS). However, selected treatment populations with DES contraindications such as patients who cannot sustain 6-12 months of dual antiplatelet therapy (DAPT) remain candidates for BMS implantations.

We present a patient with lymphangioleiomyomatosis (LAM) on long-term sirolimus (now 79 months) who has had a second successful pregnancy. The second pregnancy on uninterrupted low-dose sirolimus (plasma levels 3-5 mg/L) was uncomplicated both with respect to mother and child suggesting that low-dose sirolimus might be safe in selected pregnant patients with stable LAM. The long-term time course in this patient is in agreement with recent reports of a long-term beneficial effect of sirolimus in LAM.

Background: Currently available antiarrhythmic agents for the treatment of atrial fibrillation (AF) have important limitations, leaving an unmet need for safe and effective therapy. Ranolazine is an approved antianginal agent with a favorable safety profile and electrophysiologic properties suggesting a potential role in the treatment of AF.

Objective: The purpose of this study was to assess the safety and efficacy of ranolazine in the prevention of AF recurrence after successful electrical cardioversion and to ascertain the most appropriate dose of this agent.

To date only sparse data are available on trends and changes in indications, patient's characteristics, and clinical outcome of patients undergoing carotid artery stenting (CAS) in clinical practice. From February 1996 to December 2010, 6,116 CAS procedures were performed in 5,976 patients at 36 hospitals within the prospective, multicenter CAS registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte. Median age of patients was 71 years, 71.

Objectives: This study sought to assess the clinical safety and effectiveness of the Resolute zotarolimus-eluting stent (R-ZES) in patients with in-stent restenosis (ISR) from 2 large trials.

Background: ISR treatment is associated with higher rates of subsequent cardiac events compared with treatment of de novo lesions. Although drug-eluting stents (DES) are an option, second-generation DES are largely untested in the treatment of ISR.

Background: Carotid artery stenting (CAS) is increasingly used for treatment of severe carotid artery stenosis, but only few procedural risk factors for complications of CAS are clearly defined yet. A possible impact of the patient's gender on the outcome of patients undergoing CAS has not been investigated properly and only little information about this topic is available so far.

Methods: We analysed data of the German prospective, multicenter CAS Registry of the Arbeitsgemeinschaft leitende kardiologische Krankenhausärzte.

Background: Treatment of lesions in small coronary arteries by percutaneous transluminal coronary intervention is limited by a high recurrence rate. We assessed the use of a paclitaxel-coated balloon in this indication.

Methods: One-hundred eighteen patients with stenoses in small coronary vessels were treated by a paclitaxel-coated balloon (3 microg/mm(2)).

Background: Treatment of in-stent restenosis with paclitaxel-coated balloon catheter as compared with plain balloon angioplasty has shown surprisingly low late lumen loss at 6 months and fewer major adverse cardiac events up to 2 years. We compared the efficacy and safety of a paclitaxel-coated balloon with a paclitaxel-eluting stent as the current standard of care.

Methods And Results: One hundred thirty-one patients with coronary in-stent restenosis were randomly assigned to treatment by a paclitaxel-coated balloon (3 microg/mm2) or a paclitaxel-eluting stent.
