Relationship between coronary diastolic pressure indexes during the wave ‐free period and a novel pressure‐derived index: Diastolic pressure ratio at the optimal point

AbstractObjectivesWe aimed to determine the diastolic pressure ratio at the optimal point (DROP) using a simple measurement algorithm and to compare DROP with distal coronary ‐to‐aortic pressure ratios during the wave‐free period (PRWFP) and at the mid ‐diastolic point (PRMD).MethodsDistal coronary and aortic pressures were measured from color pressure images of 440 beats in 48 patients with coronary stenoses. The DROP measurement point was 67% for one beat between the two rising points on the aortic pressure curve according to the distribution of the wave ‐free period and the mid‐diastolic point.ResultsDROP correlated closely with PRWFP (r  = 0.993,P

Abstract Secondary prevention with medications is essential for the better prognosis of patients who have experienced cardiovascular events. We aimed to evaluate the use of guideline-based medications for secondary prevention in older adults in the community settings after discharge following percutaneous coronary intervention (PCI). A retrospective cohort study was conducted using anonymized claims data of older beneficiaries in a suburban city of Japan between April 2012 and March 2015. The prescriptions of antiplatelets, statins, angiotensin-converting enzyme inhibitors (ACEi)/angiotensin II receptor blockers (...

There is scarce evidence that the erythrocyte sedimentation rate (ESR) could efficiently improve the prediction accuracy of the Global Registry of Acute Coronary Events (GRACE) risk score in cases of ST-elevation myocardial infarction (STEMI). A cohort of 1094 STEMI patients undergoing primary percutaneous coronary intervention was retrospectively recruited. Patients were categorized based on the ESR values. Final endpoints included cardiovascular death and major adverse cardiovascular event (MACE) occurrence. The predictive value of combined models with the GRACE score and ESR was assessed by receiver operating character...

AbstractAcute kidney injury (AKI) is common in patients undergoing percutaneous coronary intervention (PCI). One risk factor for AKI is periprocedural hemoglobin drop level (>  3 g/dL); however, whether the relationship between hemoglobin drop and AKI is linear or nonlinear remains unknown. We aimed to investigate the relationship between periprocedural hemoglobin drop and AKI after PCI. We evaluated 14,273 consecutive patients undergoing PCI between September 2008 and March 2019. AKI was defined as an absolute or a relative increase in serum creatinine level of 0.3 mg/dL or 50%, respectively. Restricte...

ConclusionContemporary “real-world” data concerning antithrombotic treatment in AF patients undergoing PCI indicate a strong shift towards the use of NOACs instead of VKAs, along with a large subset of patients adopting an aspirin-free strategy early after index PCI, with clinical as well as treatment characteristics affecting decision-making.Trial registrationClinicalTrials.gov Identifier: NCT03362788 (First Posted: December 5, 2017)

CONCLUSIONS: In this first-in-patient experience, PZ-128 added to standard antiplatelet therapy appeared to be safe, well tolerated, and potentially reduced periprocedural myonecrosis, thus providing the basis for further clinical trials.

DiscussionThe PLA-pCi-EBO-pilot-trial evaluates the effect of visual angiographic result demonstration on disease symptoms and QoL in patients with stable CAD/CCS on top of PCI. A positive outcome of our study would encourage the routine use of angiographic picture demonstration and has thus the potential to change daily routine in the catheterization laboratory.Trial registrationGerman Clinical Trials RegisterDRKS00017524.

This study aimed to compare the long-term outcome of triple antithrombotic therapy (TAT) with that of dual antiplatelet therapy (DAPT) after AMI. This was a nationwide, propensity score-matched, case –control study of 186,112 first AMI patients, of whom 2,825 received TAT comprising aspirin, clopidogrel, and warfarin. Propensity score matching in a ratio of 1:4 by age, sex, comorbidities, and treatment was adopted, Finally, 2,813 AMI patients and 11,252 matched controls that were administered TAT and DAPT (aspirin and clopidogrel), respectively, were included in our analysis. The 12-year overall survival rate did not...

However, mechanistic proof that reducing pollution may be beneficial to prevent atherothrombotic events is limited. We aimed at appraising the impact of temporary traffic bans in a large metropolitan area on th...

Coronary artery calcifications are always challenging scenarios for interventional cardiologists. Calcium content in coronary tree directly correlates with male sex, age, Caucasian ethnicity, diabetes, and chronic kidney disease. Intracoronary imaging is useful and necessary to understand calcific lesion features and plan the best percutaneous coronary intervention strategy. Thus, accurate evaluation of patient and lesion characteristics is crucial. For this reason, definition of calcific arc, length, and thickness can suggest the best procedure before stenting and final optimization. In our modern era, different devices a...
