Angiography is the current gold standard for imaging during percutaneous coronary interventions but has significant limitations. Catheter-based intravascular imaging techniques such as intravascular ultrasound and the more recent optical coherence tomography have the potential to overcome these limitations and thus optimize clinical outcomes. In this update, we discussed the current applications of the available imaging techniques, existing evidence, continuing unmet needs, and potential areas f ...[more]

Project description:Background The role of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) is still unclear in patients with acute myocardial infarction acute myocardial infarction. This study aimed to evaluate the long-term impact of IVUS-guided PCI in patients with acute myocardial infarction. Methods and Results Among a total of 13 104 patients with acute myocardial infarction, enrolled in the Korea Acute Myocardial Infarction Registry-National Institutes of Health, we selected patients who underwent PCI with second-generation drug-eluting stent implantation. The primary outcome was the risk of target lesion failure at 3 years. Among the study population, 1887 patients (21.0%) underwent IVUS-guidance, and 7120 patients (79.0%) underwent angiography-guidance for second-generation drug-eluting stent implantation. IVUS-guided PCI was associated with a significantly lower risk of target lesion failure at 3 years (4.8% versus 8.0%; hazard ratio [HR], 0.59; 95% CI, 0.47 to 0.73; P<0.001) compared with angiography-guided PCI. The difference was driven mainly by a lower risk of cardiac death and target vessel myocardial infarction. The results were consistent after confounder adjustment by multiple sensitivity analyses. Moreover, quartile analysis of volume of IVUS use showed that higher IVUS use was associated with a decreased risk of 3-year target lesion failure (adjusted HR, 0.58; 95% CI, 0.45 to 0.75; P<0.001 for quartile 1 versus 4; P<0.001 for trend comparison across all quartiles). Conclusions In patients with acute myocardial infarction who underwent PCI with second-generation drug-eluting stent implantation, the use of IVUS guidance was associated with a significant reduction in 3-year target lesion failure, mainly driven by hard end points, such as cardiac death and target vessel myocardial infarction.

Project description:BackgroundA novel software ("Dynamic Coronary Roadmap") was developed, which offers a real-time, dynamic overlay of the coronary tree on fluoroscopy. Once the roadmap has been automatically generated during angiography it can be used for navigation during percutaneous coronary interventions (PCI). As a feasibility study, we aimed to investigate the feasibility of real-time dynamic coronary roadmapping and consecutive coronary overlay during elective PCI.Methods and resultsWe studied 936 overlay runs, created following the same amount of angiographies, which were generated during 36 PCIs. Feasibility of dynamic coronary roadmapping was analyzed using a dedicated software tool. Roadmap quality (correct dynamic imaging of the vessels without relevant artefacts or missing parts) was distinguished from overlay quality (congruence of dynamic coronary roadmapping and coronary anatomy). Additionally, we assessed procedural success and the occurrence of major cardiac and cerebrovascular events (MACCE). Roadmap quality was defined as "fit for use" in 99.5%. In 97.4% of runs overlay quality was deemed "fit for use". Overall, we observed low inter and intra observer variability (ICC R?=?0.84 for roadmap quality and R?=?0.75 for overlay quality). Procedural success rate was 100%. MACCE occurred in two (5.6%) patients during post-interventional in-hospital stay and were not software-related.ConclusionsDynamic coronary roadmapping provides in >?98% of cases sufficient roadmap quality with an anatomically correct overlay of the coronary vessels with good inter and intra observer variability. Future randomized studies are warranted to test possible advantages like procedure time reduction and less consumption of contrast medium.

Project description:BackgroundThe COVID-19 pandemic has severely impacted healthcare delivery and patient outcomes globally.AimsWe aimed to evaluate the influence of the COVID-19 pandemic on the temporal trends and outcomes of patients undergoing percutaneous coronary intervention (PCI) in Michigan.MethodsWe compared all patients undergoing PCI in the BMC2 Registry between March and December 2020 ("pandemic cohort") with those undergoing PCI between March and December 2019 ("pre-pandemic cohort"). A risk-adjusted analysis of in-hospital outcomes was performed between the pre-pandemic and pandemic cohort. A subgroup analysis was performed comparing COVID-19 positive vs. negative patients during the pandemic.ResultsThere was a 15.2% reduction in overall PCI volume from the pre-pandemic (n = 25,737) to the pandemic cohort (n = 21,822), which was more pronounced for stable angina and non-ST-elevation acute coronary syndromes (ACS) presentations, and between February and May 2020. Patients in the two cohorts had similar clinical and procedural characteristics. Monthly mortality rates for primary PCI were generally higher in the pandemic period. There were no significant system delays in care between the cohorts. Risk-adjusted mortality was higher in the pandemic cohort (aOR 1.26, 95% CI 1.07-1.47, p = 0.005), a finding that was only partially explained by worse outcomes in COVID-19 patients and was more pronounced in subjects with ACS. During the pandemic, COVID-19 positive patients suffered higher risk-adjusted mortality (aOR 5.69, 95% CI 2.54-12.74, p<0.001) compared with COVID negative patients.ConclusionsDuring the COVID-19 pandemic, we observed a reduction in PCI volumes and higher risk-adjusted mortality. COVID-19 positive patients experienced significantly worse outcomes.

Project description:BackgroundRandomized clinical trials demonstrated the benefits of percutaneous coronary interventions (PCI) in diverse clinical settings. Patients with cancer were not routinely included in these studies.Methods/resultsLiterature search of PubMed, Cochrane, Medline, SCOPUS, EMBASE, and ClinicalTrials was conducted to identify studies that assessed one-year all-cause, cardiovascular and non-cardiovascular mortality in patients with historical or active cancer. Using the random effects model, we computed risk ratios (RRs) and standardized mean differences and their 95% confidence intervals for the dichotomous and continuous measures and outcomes, respectively. Of 171 articles evaluated in total, 5 eligible studies were included in this meta-analysis. In total, 33,175 patients receiving PCI were analyzed, of whom 3323 patients had cancer and 29,852 no cancer history. Patients in the cancer group had greater all-cause mortality [RR 2.22 (1.51-3.26; p<0.001)], including cardiovascular mortality [RR 1.34 (1.1-1.65; p=0.005)] and non-cardiovascular mortality [RR 3.42 (1.74-6.74; p≤0.001], at one-year compared to non-cancer patients. Patients in the cancer group had greater one-month all-cause mortality [RR 2.01 (1.24-3.27; p=0.005)] and greater non-cardiovascular mortality [RR 6.87 (3.10-15.21; p≤0.001)], but no difference in one-month cardiovascular mortality compared to non-cancer patients. Meta-regression analyses showed that the difference in one-year all-cause and cardiovascular mortality between both groups was not attributable to differences in baseline characteristics, index PCI characteristics, or medications prescribed at discharge.ConclusionsPatients with cancer undergoing PCI have worse mid-term outcomes compared to non-cancer patients. Cancer patients should be managed by a multi-specialist team, in an effort to close the mortality gap.

Project description:Background Long-term outcomes of percutaneous coronary intervention (PCI) based on patients' decision-making ability have not been studied. Our objective was to assess long-term outcomes after PCI in patients who provided individual versus surrogate consent. Methods and Results Data were collected retrospectively for patients who underwent PCI at Cleveland Clinic between January 1, 2015 and December 31, 2016. Inclusion criteria consisted of hospitalized patients aged ≥20 years who had PCI. Patients with outpatient PCI, or major surgery 30 days before or 90 days after PCI, were excluded. Patients who underwent PCI with surrogate consent versus individual consent were matched using the propensity analysis. Kaplan-Meier, log rank, t-statistic, and χ2 tests were used for statistical analysis. The study was approved by the Institutional Review Board at Cleveland Clinic, Ohio. Of 3136 patients who underwent PCI during the study period, 183 had surrogate consent. Propensity matching yielded 149 patients from each group. Two-year all-cause mortality was significantly higher in the surrogate consent group (38 [25.5%] versus 16 [10.7%] deaths, log-rank χ2=10.16, P<0.001). The 2-year major adverse cardiac events rate was also significantly higher in the surrogate consent group (60 versus 36 events, log-rank χ2=8.36, P=0.003). Conclusions Patients with surrogate consent had significantly higher all-cause mortality and higher major adverse cardiac events when compared with patients with individual consent. This study emphasizes the fact that patients with an inability to give consent are at high risk and may need special attention in postprocedural and postdischarge care.

Project description:Dual oral antiplatelet therapy, aspirin plus thienopyridine, has permitted a rapid increase in the use of coronary intervention procedures. Clopidogrel is the thienopyridine of choice for dual antiplatelet therapy in patients treated with percutaneous coronary intervention. However, there are two issues with clopidogrel: (1) clopidogrel's antiplatelet activity is delayed because the drug needs to be metabolized into its active form and (2) variability in patient response to clopidogrel has been demonstrated. To overcome these shortcomings of clopidogrel, new more potent inhibitors of P2Y12 receptors, which have a more rapid onset of action have been introduced for clinical evaluation. This article is a nonexhaustive review of the literature and concentrates on prasugrel, a third-generation, oral thienopyridine. The purpose is to summarize the current knowledge about the benefits and risks of prasugrel and to outline the most prudent strategies for the drug's clinical use.

Project description:BackgroundCardiovascular disease and cancer increasingly coexist, yet relationships between cancer and long-term cardiovascular outcomes post-percutaneous coronary intervention (PCI) are not well studied.Methods and resultsWe examined stented PCI patients at Duke (1996-2010) using linked data from the Duke Information Systems for Cardiovascular Care and the Duke Tumor Registry (a cancer treatment registry). Our primary outcome was cardiovascular mortality. Secondary outcomes included composite cardiovascular mortality, myocardial infarction, or repeat revascularization and all-cause mortality. We used adjusted cause-specific hazard models to examine outcomes among cancer patients (cancer treatment pre-PCI) versus controls (no cancer treatment pre-PCI). Cardiovascular mortality was explored in a cancer subgroup with recent (within 1 year pre-PCI) cancer and in post-PCI cancer patients using post-PCI cancer as a time-dependent variable. Among 15 008 patients, 3.3% (n=496) were cancer patients. Observed rates of 14-year cardiovascular mortality (31.4% versus 27.7%, P=0.31) and composite cardiovascular death, myocardial infarction, or revascularization (51.1% versus 55.8%, P=0.37) were similar for cancer versus control groups; all-cause mortality rates were higher (79.7% versus 49.3%, P<0.01). Adjusted risk of cardiovascular mortality was similar for cancer patients versus controls (hazard ratio 0.95; 95% CI 0.76 to 1.20) and for patients with versus without recent cancer (hazard ratio 1.46; 95% CI 0.92 to 2.33). Post-PCI cancer, present in 4.3% (n=647) of patients, was associated with cardiovascular mortality (adjusted hazard ratio 1.51; 95% CI 1.11 to 2.03).ConclusionsCancer history was present in a minority of PCI patients but was not associated with worse long-term cardiovascular outcomes. Further investigation into PCI outcomes in this population is warranted.

Project description:ObjectiveTo determine whether kidney stone history is associated with adverse outcomes after percutaneous coronary intervention (PCI). Kidney stone formers have an increased risk of developing coronary artery disease; however, whether these patients have worse cardiac outcomes is unknown.Materials and methodsWe identified adult patients who underwent first-time PCI in Vanderbilt University Medical Center (VUMC) Synthetic Derivative from 2008 to 2016 (n = 11,289) and in a nationwide database of Taiwan (NHIRD) from 2005 to 2012 (n = 155,762). Odds ratios (ORs) of 30-day in-hospital mortality and hazard ratios (HRs) of 1-year and 3-year adverse outcomes associated with kidney stone history were estimated using a propensity score approach.ResultsOverall, 294 and 12,286 stone formers undergoing PCI were identified in the VUMC and NHIRD, respectively. After matching, stone formers at VUMC were at higher risks of 30-day in-hospital mortality (OR 2.79, 95% CI 1.15-6.69) and 1-year (HR 1.59, 95% CI 1.13-2.24) and 3-year (HR 1.36, 95% CI 1.02-1.81) myocardial infarction. In the NHIRD, kidney stone history was associated with 1-year (HR 1.12, 95% CI 1.03-1.21) and 3-year (HR 1.14, 95% CI 1.06-1.22) myocardial infarction. In a sensitivity analysis, stone formers undergoing kidney stone surgery were marginally associated with 30-day in-hospital mortality (OR 1.21, 95% CI 0.99-1.48) and were associated with 3-year myocardial infarction (HR 1.13, 95% CI 1.02-1.25).ConclusionKidney stone history is associated with poorer cardiac outcomes after PCI. Improving secondary cardiac prevention strategies after PCI may be necessary for patients with a history of kidney stone disease.

Project description:The aim of this study is to investigate sex-related impacts on clinical outcomes after percutaneous coronary intervention (PCI). We analyzed 90,305 patients (29.0% of women) with the first episode of coronary artery disease who underwent PCI from the Korean National Health Insurance claims database between July 2013 and June 2017. Women were significantly older than men (71.5 ± 10.5 vs. 61.8 ± 11.7 years, p < 0.001). The study population had a median follow-up of 2.2 years (interquartile range, 1.2-3.3). In the propensity-score matched angina population (15,104 pairs), the in-hospital mortality of women was not different from men (odds ratio, 0.87; 95% confidence interval: 0.71-1.08, p = 0.202). However, the post-discharge mortality of women was significantly lower (hazard ratio, 0.74; 95% confidence interval: 0.69-0.80, p < 0.001) than that of men. In the propensity-score matched acute myocardial infarction (AMI) population (8,775 pairs), the in-hospital mortality of women was significantly higher than that of men (odds ratio, 1.19; 95% confidence interval: 1.05-1.34, p = 0.006). Meanwhile, there was no difference in mortality after discharge (hazard ratio, 0.98; 95% confidence interval: 0.91-1.06, p = 0.605). The post-discharge mortality of women was not higher than men under the contemporary PCI treatment. Altered sex-related impacts on clinical outcomes might be attributed to improved medical and procedural strategies.

Project description:In recent years, there have been several reports on robotic-assisted percutaneous coronary intervention (R-PCI), but few studies have been conducted on R-PCI performed under intravascular imaging guidance. To elucidate the periprocedural and postoperative 30-day outcomes of intravascular imaging-guided R-PCI, we performed a retrospective observational study on all patients in 102 consecutive cases who underwent R-PCI under intravascular imaging guidance at a single center in Japan from June 12, 2019 to February 18, 2021. The primary end point was 30-day survival, and the secondary end point was the incidence of complications. Intravascular imaging-guided R-PCI was performed 110 times in total on 125 lesions. The medians of procedural time, fluoroscopy time, contrast volume, patient entrance skin dose, and radiation exposure to the main operator were 49 min, 16 min, 67 mL, 0.62 Gy, and 0 μSv, respectively. Furthermore, 60.0% of target lesion branches were American College of Cardiology Foundation/American Heart Association classification type B2 or type C. However, in all cases, lesion dilatation was successful, and the final Thrombolysis in Myocardial Infarction flow grade was 3. The combination of manual operation was required in 12.7% of all cases, but 30-day survival was confirmed in all cases. There were two problems at the puncture site. One small distal branch artery dissection occurred due to manual operation, but no cardiovascular events (myocardial infarction, stroke) occurred and no target lesion restenosis was observed within 30 days of R-PCI. Hence, R-PCI using intravascular imaging demonstrated highly satisfactory treatment outcomes, and no complication caused by robotic operation was observed.
