Objective: To determine the prevalence of percutaneous coronary intervention (PCI) related myocardial damage (injury or myocardial infarction), investigate several cardiac biomarkers, explore possible risk factors and assess survival in patients undergoing elective PCI.
Methods: Patients >18 years of age who had undergone an elective PCI at Huashan hospital in Shanghai, China from October 2016 to June 2017 and had baseline and post-PCI results available for four cardiac biomarkers (cTnT, CK-MB mass, hs-CRP and NT-ProBNP) were eligible. Patients were separated into two groups according to whether or not they had PCI related myocardial damage.
Results: Of the 143 patients who were eligible for the study, 75 (52%) were classified as ‘controls,’ and 68 (48%) had PCI related myocardial damage. Of the 68 patients, 64 (45%) had PCI related myocardial injury and 4 (3%) had PCI related myocardial infarction. Elderly Chinese patients, with high systolic blood pressure on admission and who required multiple coronary segments for PCI had a high risk of myocardial damage. Relative cTnT or relative CK-MB mass may be useful cardiac biomarkers for monitoring PCI related myocardial damage, especially at 24h post-PCI. There was no significant difference in survival rates between controls and those with myocardial complications.
Conclusions: PCI related myocardial damage is common but appears to have no impact on prognosis. Senior age, high systolic blood pressure and multiple coronary segments for PCI are risk factors.

Effectiveness of 'Internet Plus' remote management in improving cardiac rehabilitation outcomes in acute myocardial infarction patients.
Am J Transl Res
December 2024
Nursing Department, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine Hangzhou 310000, Zhejiang, China.
Objectives: This study evaluated the effectiveness of "Internet Plus" remote management in enhancing cardiac rehabilitation outcomes for patients with acute myocardial infarction (AMI) following percutaneous coronary intervention (PCI).
Methods: A total of 101 AMI patients post-PCI from Sir Run Run Shaw Hospital were included between December 2021 and November 2022. Patients were retrospectively categorized into two groups based on the type of care they received: the control group receiving standard post-PCI rehabilitation, and the observation group receiving remote management via "Internet Plus" for six months.
Impact of procedural and patient-related risks on 1-year outcomes for patients treated with 1-month dual antiplatelet therapy followed by P2Y12 inhibitor monotherapy after biodegradable-polymer drug-eluting stent implantation.

In clinical practice, the impact of procedural or patient-related risk factors on 1-year clinical outcomes in patients receiving 1-month of dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor monotherapy after contemporary percutaneous coronary intervention (PCI) remains unclear. Using data from the multi-center REIWA registry which included patients treated with thin-strut biodegradable polymer drug-eluting stent (BP-DES) and 1-month DAPT followed by P2Y12 inhibitor monotherapy, we assessed the primary endpoint (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, ischemic or hemorrhagic stroke, and major or minor bleeding) in patients with and without procedural (treatment of three vessels, three or more lesions, three or more stents, bifurcation with two stents, long stenting, and target of chronic total occlusion) and patient-related risk factor (renal insufficiency, anemia, peripheral vascular disease, prior or current history of heart failure and advanced age of ≥ 75 years). Among the 1,202 patients who underwent complete revascularization by PCI, 276 (23.

Aim: The objective of this study was to investigate the level of soluble suppression of tumorigenicity-2 (sST2) in patients with acute ST-segment elevation myocardial infarction (STEMI) following primary percutaneous coronary intervention (PCI), and to provide a new biomarker for clinical management and prognosis assessment.
Method: This was a prospective study. 148 STEMI patients following primary PCI were enrolled and divided into 2 groups by the median value of sST2 and afterwards followed up for 30 days to access the occurrence of major adverse cardiac events (MACEs), which were defined as cardiovascular death, heart failure and recurrent MI.
Background: The effect of worsening renal function and baseline chronic kidney disease (CKD) on outcomes in patients with chronic coronary syndrome in the setting of optimal medical therapy remains unknown.
Methods And Results: The REAL-CAD (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy With Pitavastatin in Coronary Artery Disease) study is a prospective, multicenter, randomized trial of high-dose (pitavastatin 4 mg/day) or low-dose (pitavastatin 1 mg/day) statin therapy in 12 118 patients with chronic coronary syndrome. The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, stroke, or unstable angina requiring hospitalization (major adverse cardiac and cerebral events [MACCE]).
Nationwide trends and outcomes of percutaneous coronary intervention for stable ischemic heart disease in end-stage kidney disease: a longitudinal study.

Department of Cardiovascular Medicine, University of Kansas Medical Center, Kansas City, KS, USA.
Background: Patients with end-stage kidney disease (ESKD) are at high risk for coronary artery disease. We investigate the trends and outcomes of percutaneous coronary intervention (PCI) for stable ischemic heart disease (SIHD) in patients with ESKD.
Methods: We utilized the United States Renal Data System [2010-2018] to include adult patients with ESKD on dialysis for at least 3 months who underwent PCI for SIHD.
