Project description:Background and objectivesThe influence of pre-intervention coronary physiologic status on outcomes post percutaneous coronary intervention (PCI) is not well known. We sought to investigate the prognostic implications of pre-PCI fractional flow reserve (FFR) combined with post-PCI FFR.MethodsA total of 1,479 PCI patients with pre-and post-PCI FFR data were analyzed. The patients were classified according to the median values of pre-PCI FFR (0.71) and post-PCI FFR (0.88). The primary outcome was target vessel failure (TVF) at 2 years.ResultsThe risk of TVF was higher in the low pre-PCI FFR group than in the high pre-PCI FFR group (hazard ratio, 1.82; 95% confidence interval, 1.15-2.87; p=0.011). In 4 group comparisons, the cumulative incidences of TVF at 2 years were 3.8%, 4.1%, 4.8%, and 10.2% in the high pre-/high post-, low pre-/high post-, high pre-/low post-, and low pre-/low post-PCI FFR groups, respectively. The risk of TVF was the highest in the low pre-/low post-PCI FFR group among the groups (p values for comparisons <0.05). In addition, the high pre-/low post-PCI FFR group presented a comparable risk of TVF with the high post-PCI FFR groups (p values for comparison >0.05). When the prognostic value of the post-PCI FFR was evaluated according to the pre-PCI FFR, the risk of TVF significantly decreased with an increase in post-PCI FFR in the low pre-PCI FFR group, but not in the high pre-PCI FFR group.ConclusionsPre-PCI FFR was associated with clinical outcomes after PCI, and the prognostic value of post-PCI FFR differed according to the pre-PCI FFR.Trial registrationClinicalTrials.gov Identifier: NCT04012281.

Project description:PurposeTo determine the location of coronary atherosclerosis distribution observed in patients with chronic kidney disease (CKD).MethodsA cross-sectional study was conducted using the database of cardiovascular medicine data from Saitama Sekishinkai Hospital to clarify the association between renal function and angiographic characteristics of coronary atherosclerosis. In total, 3268 patients who underwent percutaneous coronary intervention were included. Propensity score matching revised the total to 1772. The association of renal function with the location and/or distribution of coronary atherosclerosis lesions was then examined.ResultsOverall, coronary lesion was observed in the left anterior descending coronary artery (LAD) in 56% patients, whereas 28% and 22% were in the right coronary artery (RCA) and left circumflex coronary artery (LCX), respectively. LAD was most affected and observed in 57% patients with stage 1 CKD. RCA was second-most affected, at 26% CKD stage 1, but it increased to 31%, 38%, and 59% in CKD 3, 4, and 5, respectively. In CKD 5 patients, the RCA was the most affected artery (59%), with 41% LAD lesions. Logistic regression analysis after propensity score matching showed that the odds ratios for an RCA lesion was 3.658 in CKD 5 (p = .025) compared with CKD 1 after adjusting for traditional risk factors.ConclusionThe prevalence of RCA lesions, but not LAD or LCX lesions, increased with increasing CKD stage. The pathophysiology of coronary atherosclerosis may differ by lesion location. Deterioration of renal function may affect progression of atherosclerosis more in the RCA than in the LAD or LCX.

Project description:Background Multiple percutaneous coronary interventions ( PCIs ) are considered determinant of poor outcome in patients undergoing coronary artery bypass grafting ( CABG ), but scarce data exist to substantiate this. Methods and Results Patients who underwent CABG without history of prior PCI or with PCI performed >30 days before surgery were selected for the present analysis from the prospective, multicenter E-CABG (European Multicenter Study on Coronary Artery Bypass Grafting) registry. Out of 6563 patients with data on preoperative SYNTAX (Synergy between PCI With Taxus and Cardiac Surgery) score, 1181 patients (18.0%) had undergone PCI >30 days before CABG . Of these, 11.6% underwent a single PCI , 4.4% 2 PCI s, and 2.1% ≥3 PCI s. PCI of a single main coronary vessel was performed in 11.3%, of 2 main vessels in 4.9%, and of 3 main vessels in 1.6% of patients. Multivariable analysis showed that differences in early mortality and other outcomes were not significantly different in the study cohorts. The adjusted hospital/30-day mortality rate was 1.8% in patients without history of prior PCI , 1.9% in those with a history of 1 PCI , 1.4% after 2 PCI s, and 2.5% after ≥3 PCI s (adjusted P=0.8). The adjusted hospital/30-day mortality rate was 2.0% in those who had undergone PCI of 1 main coronary vessel, 1.3% after PCI of 2 main vessels, and 3.1% after PCI of 3 main coronary vessels (adjusted P=0.6). Conclusions Multiple prior PCI s are not associated with increased risk of early adverse events in patients undergoing isolated CABG . The present results are conditional to survival after PCI and should not be viewed as a support for a policy of multiple PCI as opposed to earlier CABG .

Project description:Although current guidelines recommend ?-blocker after acute myocardial infarction (MI), the role of ?-blocker has not been well investigated in the modern reperfusion era. In particular, the benefit of vasodilating ?-blocker over conventional ?-blocker is still unexplored.Using nation-wide multicenter Korean Acute Myocardial Infarction Registry data, we analyzed clinical outcomes of 7127 patients with acute MI who underwent successful percutaneous coronary intervention with stents and took ?-blockers: vasodilating ?-blocker (n=3482), and conventional ?-blocker (n=3645). In the whole population, incidence of cardiac death at 1 year was significantly lower in the vasodilating ?-blocker group (vasodilating ?-blockers versus conventional ?-blockers, 1.0% versus 1.9%; P=0.003). In 2882 pairs of propensity score-matched population, the incidence of cardiac death was significantly lower in the vasodilating ?-blocker group (1.1% versus 1.8%; P=0.028). Although incidences of MI (1.1% versus 1.5%; P=0.277), any revascularization (2.8% versus 3.0%; P=0.791), and hospitalization for heart failure (1.4% versus 1.9%; P=0.210) were not different between the 2 groups, incidences of cardiac death or MI (2.0% versus 3.1%; P=0.010), cardiac death, MI, or hospitalization for heart failure (3.0% versus 4.5%; P=0.003), cardiac death, MI, or any revascularization (3.9% versus 5.3%; P=0.026), and cardiac death, MI, any revascularization, or hospitalization for heart failure (4.8% versus 6.5%; P=0.011) were significantly lower in the vasodilating ?-blocker group.Vasodilating ?-blocker therapy resulted in better clinical outcomes than conventional ?-blocker therapy did in patients with acute MI in the modern reperfusion era. Vasodilating ?-blockers could be recommended preferentially to conventional ones for acute MI patients.

Project description:Invasive assessment of coronary physiology has radically changed the paradigm of myocardial revascularization in patients with coronary artery disease. Despite the prognostic improvement associated with ischemia-driven revascularization strategy, functional assessment of angiographic intermediate epicardial stenosis remains largely underused in clinical practice. Multiple tools have been developed or are under development in order to reduce the invasiveness, cost, and extra procedural time associated with the invasive assessment of coronary physiology. Besides epicardial stenosis, a growing body of evidence highlights the role of coronary microcirculation in regulating coronary flow with consequent pathophysiological and clinical and prognostic implications. Adequate assessment of coronary microcirculation function and integrity has then become another component of the decision-making algorithm for optimal diagnosis and treatment of coronary syndromes. This review aims at providing a comprehensive description of tools and techniques currently available in the catheterization laboratory to obtain a thorough and complete functional assessment of the entire coronary tree (both for the epicardial and microvascular compartments).

Project description:BackgroundRecently, sclerostin, a bone-derived protein, has been shown to play a key role in atherosclerosis progression. However, few studies have investigated the influence of sclerostin on cardiovascular disease prognosis. We investigated the relationship between serum sclerostin levels and adverse outcomes in elderly patients with stable coronary artery disease (SCAD) who were undergoing percutaneous coronary intervention (PCI).MethodsWe enrolled 310 elderly SCAD patients who underwent PCI in this study and followed them 3 years. According to the median serum sclerostin levels, subjects were stratified into a low sclerostin (low scl) group (n = 144) and a high sclerostin (high scl) group (n = 166). Time-to-event analyses were performed with the Kaplan-Meier method. Associations between sclerostin levels and main adverse cardiovascular and cerebrovascular events (MACCEs) and mortality were evaluated by Cox multivariate regression analysis. The prognostic power of predictive models was verified by the concordance index and receiver operating characteristic curve analysis.ResultsThe high scl group had a significantly higher MACCE-free rate and better survival than the low scl group. Serum sclerostin was an independent predictor and could improve the prognostic power for adverse outcomes. In addition, serum sclerostin levels were significantly associated with bone turnover markers, a lower presence of multivessel disease and a lower CCS angina class.ConclusionsSerum sclerostin is a prognostic parameter for predicting and intervening in the adverse outcomes of elderly SCAD patients undergoing PCI, which may be explained by its potential role in the bone-vascular axis.

Project description:Background: Evidence on factors associated with guideline-directed secondary prevention medication (GDPM) after percutaneous coronary intervention (PCI) and its effect on the prognosis of patients with coronary artery disease (CAD) is lacking in China. Aims: To ascertain predictors of GDPM in real-world clinical practice and to assess the effect of GDPM on clinical outcomes. Design: A retrospective cohort study. Methods: Consecutive patients admitted to Fuwai Hospital between January 2013 and December 2013 were recruited. GDPM comprised aspirin, clopidogrel, statins, β-blockers, and angiotensin-converting enzyme inhibitors/angiotensin Ⅱ receptor blockers. The primary outcome was five-year major adverse cardiovascular event (MACE) (cardiac death, myocardial infarction [MI] and unplanned revascularization). Multivariable logistic regression was used to identify predictors of prescribing GDPM. Multivariable Cox regression was used to examine the relationship between GDPM and clinical outcomes. Results: 10,067 patients were followed up for a median of 5.0 years (interquartile range: 4.3–5.2), 45.1% were prescribed with GDPM. Presenting with ST-segment elevation MI (adjusted OR = 3.252 [2.832–3.736]), prior MI (adjusted OR = 2.174 [1.948–2.425]), more stents implanted (adjusted OR = 1.063 [1.022–1.106]), overweight (adjusted OR = 1.136 [1.038–1.243]), obesity (adjusted OR = 1.274 [1.100–1.476]), diabetes (adjusted OR = 1.225 [1.115–1.344]), and hypertension (adjusted OR = 3.556 [3.196–3.956]) predicted the prescription of GDPM. Advanced age (adjusted OR = 0.556 [0.379–0.816]) was associated with lower prescription rate of GDPM. Patients with GDPM had lower rate of 5-year MACE (adjusted HR = 0.889 [0.808–0.978]) relative to those without GDPM. Conclusions: Despite the benefit of GDPM in improving the prognosis of CAD patients undergoing PCI, gaps still exist in GDPM prescription in real-world clinical practice. Our study determined target populations for physicians to strive to promote the application of GDPM.

Project description:ObjectiveEndothelial progenitor cells (EPCs) are produced in the bone marrow and mobilized to the peripheral blood playing a key role in endothelial repair. The objective of this study was to evaluate circulating EPC before and after percutaneous coronary intervention (PCI) with stent implantation and their associations with coronary restenosis and adverse cardiovascular events. Venous blood was obtained before and the day after PCI. Quantification of total white blood count and identification of EPCs (CD45-CD34+CD31+CD133/2+CD309+) through immunophenotyping by flow cytometry was performed. The primary outcome was either restenosis detected by new coronary angiography or angina with myocardial ischemia at the territory of the stented coronary artery. Secondary outcomes were angina without demonstrable myocardial ischemia, acute coronary syndrome or all-cause death.Results37 patients were followed for 1 year. The median EPC count before PCI was 320 cells/mcl and after PCI 286 cells/mcl. A decrease of EPC count was found in 65% of the patients, while 35% displayed an increase. Primary outcomes occurred in 10.8% and the secondary in 37.8% of the patients. Despite a higher level of EPC before (402 cell/mcl) and after PCI (383 cell/mcl) in patients with the secondary outcomes, there was no significant association between EPC and cardiovascular events.

Project description:BackgroundPatients with peripheral arterial disease (PAD) have known to a high risk of cardiac mortality. However, the effectiveness of the routine evaluation of coronary arteries such as routine coronary angiography (CAG) in PAD patients receiving percutaneous transluminal angioplasty (PTA) is unclear.MethodsA total of 765 consecutive PAD patients underwent successful PTA and 674 patients (88.1%) underwent routine CAG. Coronary artery disease (CAD) was defined as angiographic stenosis ≥70%. Patients were divided into three groups; 1) routine CAG and a presence of CAD (n = 413 patients), 2) routine CAG and no CAD group (n = 261 patients), and 3) no CAG group (n = 91 patients). To adjust for any potential confounders that could cause bias, multivariable Cox-proportional hazards regression and propensity score matching (PSM) analysis was performed. Clinical outcomes were evaluated by Kaplan-Meier curved analysis at 5-year follow-up.ResultsIn this study, the 5-year survival rate of patients with PAD who underwent PTA was 88.5%. Survival rates were similar among the CAD group, the no CAD group, and the no CAG group, respectively (87.7% vs. 90.4% vs. 86.8% P = 0.241). After PSM analysis between the CAD group and the no CAD group, during the 5-year clinical follow-up, there were no differences in the incidence of death, myocardial infarction, strokes, peripheral revascularization, or target extremity surgeries between the two groups except for repeat PCI, which was higher in the CAD group than the non-CAD group (9.3% vs. 0.8%, P<0.001).ConclusionPAD patients with CAD were expected to have very poor long-term survival, but they are shown no different long-term prognosis such as mortality compared to PAD patients without CAD. These PAD patients with CAD had received PCI and/or optimal medication treatment after the CAG. Therefore a strategy of routine CAG and subsequent PCI, if required, appears to be a reasonable strategy for mortality risk reduction of PAD patients. Our results highlight the importance for evaluation for CAD in patients with PAD.

Project description:ImportanceIt is uncertain whether coronary artery bypass grafting (CABG) is associated with cognitive decline in older adults compared with a nonsurgical method of coronary revascularization (percutaneous coronary intervention [PCI]).ObjectiveTo compare the change in the rate of memory decline after CABG vs PCI.Design, setting, and participantsRetrospective cohort study of community-dwelling participants in the Health and Retirement Study, who underwent CABG or PCI between 1998 and 2015 at age 65 years or older. Data were modeled for up to 5 years preceding and 10 years following revascularization or until death, drop out, or the 2016-2017 interview wave. The date of final follow-up was November 2017.ExposuresCABG (including on and off pump) or PCI, ascertained from Medicare fee-for-service billing records.Main outcomes and measuresThe primary outcome was a summary measure of cognitive test scores and proxy cognition reports that were performed biennially in the Health and Retirement Study, referred to as memory score, normalized as a z score (ie, mean of 0, SD of 1 in a reference population of adults aged ≥72 years). Memory score was analyzed using multivariable linear mixed-effects models, with a prespecified subgroup analysis of on-pump and off-pump CABG. The minimum clinically important difference was a change of 1 SD of the population-level rate of memory decline (0.048 memory units/y).ResultsOf 1680 participants (mean age at procedure, 75 years; 41% female), 665 underwent CABG (168 off pump) and 1015 underwent PCI. In the PCI group, the mean rate of memory decline was 0.064 memory units/y (95% CI, 0.052 to 0.078) before the procedure and 0.060 memory units/y (95% CI, 0.048 to 0.071) after the procedure (within-group change, 0.004 memory units/y [95% CI, -0.010 to 0.018]). In the CABG group, the mean rate of memory decline was 0.049 memory units/y (95% CI, 0.033 to 0.065) before the procedure and 0.059 memory units/y (95% CI, 0.047 to 0.072) after the procedure (within-group change, -0.011 memory units/y [95% CI, -0.029 to 0.008]). The between-group difference-in-differences estimate for memory decline for PCI vs CABG was 0.015 memory units/y (95% CI, -0.008 to 0.038; P = .21). There was statistically significant increase in the rate of memory decline after off-pump CABG compared with after PCI (difference-in-differences: mean increase in the rate of decline of 0.046 memory units/y [95% CI, 0.008 to 0.084] after off-pump CABG), but not after on-pump CABG compared with PCI (difference-in-differences: mean slowing of decline of 0.003 memory units/y [95% CI, -0.024 to 0.031] after on-pump CABG).Conclusions and relevanceAmong older adults undergoing coronary revascularization with CABG or PCI, the type of revascularization procedure was not significantly associated with differences in the change of rate of memory decline.
