Abstract
Millions of cardiomyocytes die immediately after myocardial infarction, regardless of whether the culprit coronary artery undergoes prompt revascularization. Residual ischaemia in the peri-infarct border zone causes further cardiomyocyte damage, resulting in a progressive decline in contractile function. To date, no treatment has succeeded in increasing the vascularization of the infarcted heart. In the past decade, new approaches that can target the heart's highly plastic perivascular niche have been proposed. The perivascular environment is populated by mesenchymal progenitor cells, fibroblasts, myofibroblasts and pericytes, which can together mount a healing response to the ischaemic damage. In the infarcted heart, pericytes have crucial roles in angiogenesis, scar formation and stabilization, and control of the inflammatory response. Persistent ischaemia and accrual of age-related risk factors can lead to pericyte depletion and dysfunction. In this Review, we describe the phenotypic changes that characterize the response of cardiac pericytes to ischaemia and the potential of pericyte-based therapy for restoring the perivascular niche after myocardial infarction. Pericyte-related therapies that can salvage the area at risk of an ischaemic injury include exogenously administered pericytes, pericyte-derived exosomes, pericyte-engineered biomaterials, and pharmacological approaches that can stimulate the differentiation of constitutively resident pericytes towards an arteriogenic phenotype. Promising preclinical results from in vitro and in vivo studies indicate that pericytes have crucial roles in the treatment of coronary artery disease and the prevention of post-ischaemic heart failure.

Abstract
INTRODUCTION As the primary cause of morbidity and mortality among older individuals, cardiovascular disease remains a major concern. Choosing between revascularization and medical management of elderly patients remains controversial. This study aims to evaluate the clinical implications of these treatment approaches in the context of non-ST-elevation myocardial infarction (NSTEMI) in octogenarian patients. METHODS This observational cohort study involved 41 octogenarian patients who were diagnosed with NSTEMI from 2019 to 2021 and were managed by revascularization (with either percutaneous coronary intervention, coronary artery bypass graft surgery, or both) or conservative medical therapy. All NSTEMI patients were diagnosed based on symptoms, electrocardiographic changes, and cardiac biomarkers. The study compared the short- and long-term outcomes of 13 patients in the revascularization group and 28 in the medical therapy group. RESULTS Overall, the mean patient age was 84.63 years. Eighteen patients were men (43.9%), and 23 were women (56.1%). The most prevalent disease among the sample was hypertension (34 patients, 82.9%), followed by diabetes mellitus (27 patients, 65.9%) and prior ischemic heart disease (21 patients, 51.2%). Almost all patients in the revascularization-treated group developed complications after the procedure (84.6%), while 46.4% of the patients in the medication-only group developed a complication later on. The revascularization-treated group showed higher mortality rates in both the short- and long-term (23.1% and 38.5%, respectively) compared to the medication-only group, which showed better survival rates numerically in both the short- and long-term (14.3% and 32.1%, respectively). This was not statistically significant. CONCLUSION Revascularization treatment in elderly patients with NSTEMI was associated with a higher risk of complications and a higher mortality rate compared with conservative medical management. Patients managed with only medications had a better survival rate in both the short- and long-term.

Temporal Change in the Remaining Life Expectancy in People Who Underwent Percutaneous Coronary Intervention. Am J Cardiol 2023; 187:154-161. [PMID: 36459739 DOI: 10.1016/j.amjcard.2022.10.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 10/01/2022] [Accepted: 10/21/2022] [Indexed: 11/30/2022]
Abstract
Whether percutaneous coronary intervention (PCI) is effective in improving long-term survival in an Australian PCI cohort remains unclear. We aimed to examine the change in the remaining life expectancy for patients who underwent PCI over the past decade. Patient data from the Melbourne Interventional Group were divided into four 3-year periods (2005 to 2007, 2008 to 2010, 2011 to 2013, and 2014 to 2016) for survival analysis. The primary outcome was time to death after PCI. Kaplan-Meier survival curves for overall survival were constructed to estimate the 5-year survival. To extrapolate the overall survival curve to the lifetime time horizon, 6 parametric survival distributions were fitted to the individual patient-level data against the Kaplan-Meier curve. The best fit distribution was selected based on goodness-of-fit statistics and expert opinion. The combination of annual mortality post-PCI from the parametric survival analysis and the background mortality by age informed the overall mortality rate. The life expectancy was compared with the general Australians. In addition, the utility weight of post-PCI patients was used to estimate the quality-adjusted life years gained. A total of 27,301 patients with a mean age of 64.4 ± 12 years were included. The base-case results showed that over the 4 time periods, the remaining life expectancy for patients aged 64.4 years on average at the time of PCI remained relatively stable except for period 4: 18.12 years (2005 to 2007), 17.56 years (2008 to 2010), 18.39 years (2011 to 2013), and 17.25 years (2014 to 2016), respectively. The quality-adjusted life years gained showed a similar trend: 14.86 (2005 to 2007), 14.40 (2008 to 2010), 15.07 (2011 to 2013), and 14.13 (2014 to 2016) separately. In conclusion, the widened gap in life expectancy in post-PCI patients versus the general Australian over the 2014 to 2016 period suggests the need for improved implementation of prevention strategies for coronary heart disease. Enhanced disease management after PCI that lowers residual mortality risk is recommended to extend the survival of patients with coronary heart disease.

Abstract
Background: Accumulated studies have revealed that heart rates are associated with all-cause mortality in cardiac surgery patients, but the results remain controversial. This meta-analysis aimed to evaluate the predictive value of increased perioperative heart rate for all-cause mortality after cardiac surgery. Methods: We searched PubMed, Embase, Web of Science, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases for studies from inception to October 11, 2021. Two researchers independently screened the studies. Titles, authors, publication years, and hazard ratios were extracted. We used a random-effects model to combine the HRs and 95% confidence intervals. Several subgroup analyses were conducted. Statistical significance was set at p < .05. Results: Eleven studies were included in the meta-analysis of 33,849 patients and 3166 (9.4%) deaths. The HR of higher perioperative heart rates was 2.09 (95% CI 1.53-2.86, p < .001, I2 = 81%). The HR with a 10-bpm increase in preoperative heart rate was 1.19 (95% CI 1.11-1.26, p < .001, I2 = 51%). Subgroup analysis showed patients with higher preoperative heart rates had an HR of 1.88 (95% CI 1.51-2.34, p < .001, I2 = 0%), and patients with a higher postoperative heart rate had an HR of 2.29 (95% CI 1.28- 4.09, p < .0001, I2 = 91%) compared to patients with lower postoperative heart rates. Conclusion: Increased perioperative heart rate is associated with all-cause mortality in patients undergoing cardiac surgery.

Abstract
Atrial high rate episodes (AHRE) confers increased morbidity and mortality amongst patients with permanent pacemaker implantation (PPI). The incidence of AHREs and it's clinical predictors in Indian patients without prior history of atrial fibrillation (AF) are not well understood. A total of 100 dual-chamber PPI patients, who had no prior history of AF, underwent pacemaker interrogation starting from a minimum of 1 month after implantation to detect any AHREs. The incidence of AHREs was 17% at a mean follow up 15.2 ± 7.5 months. Only right ventricular apical lead position was found to have an independent association with AHREs (OR: 3.50, 95% CI: 1.02-12.03; p = 0.04).

Abstract
In-stent restenosis and stent thrombosis are the major concerns while choosing a coronary stent. This single-centre, retrospective study evaluated the one and three-year clinical outcomes following implantation of Yukon Choice Flex (YCF) sirolimus-eluting stent. A total of 168 consecutive patients with 217 lesions underwent stenting with YCF stent. The presentation was with acute coronary syndrome in 158 (94%) patients. At 3 years, 9 (5.3%) patients died due to cardiac cause. Myocardial infarction, and definite stent thrombosis occurred in 10 (6%) and 4 (2.4%) patients respectively. Redo stenting and coronary artery bypass surgery was performed in 3 (1.8%) and 1 (0.6%) patient respectively. The use of YCF sirolimus eluting stent was associated with a favourable safety and efficacy profile at one and three-years of follow-up in a high-risk population.

Abstract
Background Low socioeconomic status (SES) is an important prognosticator for those with acute myocardial infarction (AMI), having previously been described to be associated with increased short-term mortality. Whether this effect persists over time, and whether access to cardiac interventions is equitable within Canada’s universal health care system, remains unknown. Methods We conducted a systematic review to determine the associations of SES with mortality and access to a spectrum of interventions including cardiac catheterization, revascularization, and cardiac rehabilitation. Electronic databases (EMBASE and MEDLINE) were searched in March 2019 and December 2019. Original studies from Canada examining associations between SES and any of the above outcomes in AMI patients were included. Meta-analyses were conducted using random effects models. Results Nineteen studies were included, 11 of which could be meta-analyzed. Low SES was associated with a 48% and 34% increase in short-term and intermediate-term mortality, respectively. There was a trend toward increased long-term mortality more than 1-year post-event (pooled odds ratio [OR] 1.34 [95% confidence interval {CI} 0.95-1.88]). Low SES was also associated with lower rates of cardiac catheterization (pooled OR 0.80 [95% CI 0.65-0.99]) and revascularization (pooled OR 0.76 [95% CI 0.63-0.90]) post-AMI. Studies on cardiac rehabilitation showed reduced access and participation in low-SES groups. Conclusions Low SES is associated with not only increased mortality post-AMI, but also reduced access to cardiac interventions that have demonstrated benefits for mortality and morbidity. Interventions that improve access to catheterization, revascularization, and cardiac rehabilitation for low-SES populations are needed if true equitable care in Canada is desired.

Abstract
BACKGROUND In modern cardiology, anticoagulation and antiaggregation are key components of current treatment strategies. However, in patients treated with anticoagulation and antiplatelet substances, bleeding is a major risk. FINDINGS In all major cardiovascular diseases, a multitude of studies have shown a positive impact of antithrombotic treatment on cardiovascular death. In patients with higher bleeding risks, recent studies showed the safety of reducing the period of dual antiplatelet therapy (DAPT), i.e., after percutaneous coronary intervention. In patients with coronary artery disease and atrial fibrillation (AF), triple therapy including DAPT and anticoagulation is associated with very high bleeding risks. However, recently published data showed the safety of direct oral anticoagulants (DOACs) and P2Y12 inhibitors only compared to vitamin K antagonist (VKA) and DAPT. Anticoagulation in nonvalvular AF reduces major cerebrovascular ischemic events. However, the inherent cerebrovascular bleeding risk is an important concern of this treatment. With the advent of DOACs, this risk could be reduced compared to VKA. Furthermore, anticoagulation and antiaggregation are crucial after treatment of valve disease, both after surgical and interventional procedures. Even in heart failure, new data show benefits using antithrombotic substances. CONCLUSIONS Anticoagulation and antiaggregation are of major prognostic relevance in cardiovascular diseases. However, the inherent bleeding risk has to be considered.

Abstract
BACKGROUND High blood pressure (BP) may impair renal function following percutaneous coronary intervention (PCI). However, the predictability of renal progression based on admission and discharge BP and BP threshold values remains unclear. METHODS A total of 8,176 adult patients who underwent PCI at Seoul National University Hospital from 2006 to 2016 were retrospectively analyzed. Renal progression was defined as a doubling of serum creatinine levels, ≥50% decrease of the estimated glomerular filtration rate, or development of end-stage renal disease. The risk of renal progression according to admission BP (any time) and discharge BP (8:00-10:00 am) was evaluated by multivariable Cox and additive generalized models with penalized splines. RESULTS During a median follow-up of 7 years (maximum: 13 years), 9.3% of patients (n = 758) reached renal progression. BP between admission and discharge showed a low correlation, and all BP parameters showed a nonlinear relationship with renal progression. Systolic BP at discharge (SBPd) was selected as the best predictor of renal progression because the delta for the Akaike information criterion from the baseline model to the model with BP parameters was the lowest. The risk of renal progression started to increase at SBPd ≥ 125 mm Hg. This increasing risk of renal progression with SBPd ≥ 125 mm Hg remained significant, despite adjusting for the competing risk of all-cause death. CONCLUSIONS High SBPd is associated with renal progression following PCI, particularly when it is ≥125 mm Hg. This can be used as a risk classification and potential target of renoprotective therapies.

Abstract
Background There is limited evidence of non-ST elevation acute coronary syndrome (NSTE-ACS) in patients aged 80 or older in Vietnam. Aim To describe the clinical characteristics of patients aged≥80 with NSTE-ACS in Vietnam, and to examine the effect of percutaneous coronary intervention (PCI) on adverse outcomes. Methods Consecutive patients aged ≥80 with a diagnosis of NSTE-ACS admitted to two tertiary hospitals in Vietnam from 12/2018 to 06/2019 were recruited. The major outcomes were: (1) the composite of all-cause mortality, recurrent myocardial infarction and stroke, (2) re-admission rate during 3 months. Cox proportional-hazards regressions were conducted to examine the impact of PCI on the study outcomes, with results presented as hazard ratios (HR) and 95% confidence intervals (CI). Results There were 120 participants, mean age 84.8 ± 3.8, 50% were female. Angiography and PCI were performed in 42 participants (35.0%). Most of the participants had multimorbidity and multiple coronary vessel disease. Compared to participants who did not receive PCI, participants who received PCI had significantly lower rates of adverse events during hospitalisation and during 3 months of follow up. Cox proportional hazards models adjusted to age and GRACE score show that PCI was significantly associated with reduced the composite outcome of all-cause mortality, recurrent myocardial infarction and stroke during 3 months follow-up (adjusted HR 0.32, 95%CI 0.12–0.86). PCI was also associated with reduced re-admission. Conclusions The rate of PCI was low in the very elderly patients with NSTE-ACS in this study, although PCI was significantly associated with reduced adverse outcomes.

Abstract
The proportion of the elderly in the total population of the world is growing, and the number of elderly patients with coronary chronic total occlusions (CTO) is huge. The elderly patients often have more extensive coronary artery disease, more severe ischemic burden and higher risk of cardiovascular events, as compared to younger patients, and thereby they might greatly benefit from coronary revascularization, even though they may have higher risk of operative complications. Most interventional cardiologists are more likely to be reluctant to operate complex percutaneous coronary intervention (PCI) in elderly patients. The latest refinements in dedicated CTO-PCI equipment and techniques have led to high rates of success and low complications rates and have made the CTO-PCI procedures safe and effective among the elderly patients. However, up to now, there is no widely recognized consensus or guideline on treatment strategy of elderly CTO patients, and the prognosis in this population is unknown. In this review, we aim to provide an overview of the current evidence and future perspectives on PCI in elderly patients with CTOs.
