{"title":"The Multi-Artery Fractional Flow Reserve (FFR) Method in The Percutaneous Coronary Intervention (PCI) Practice","authors":"Ilan A Yaeger","doi":"10.33552/ojcr.2020.03.000573","DOIUrl":"https://doi.org/10.33552/ojcr.2020.03.000573","url":null,"abstract":"Current single-artery FFR-oriented coronary stenosis severity assessment methods (resting P d /P a , wave-free iFR and hyperemic FFR) are used successfully in single vessel disease (SVD) cases. In such cases the stenotic artery is in an independent stand-alone position with a proximal intracoronary aortic driving pressure. The treatment decision criteria of each method (FFR threshold value and FFR ‘grey range’) apply to FFR of the artery (denoted FFR true ) which is the remnant fraction left in the stenotic artery of the calculated virtual blood flow of the very same artery prior to the onset of stenosis. As FFR true can be expressed in terms of the total stenotic resistance R s of the artery and the microvascular resistance Rmv associated with the artery, FFR true can be also justifiably regarded as an ad-hoc intrinsic property of the stenotic artery. It doesn’t change unless the artery undergoes revascularization, turning its FFR true to nearly 1.00. The general scenario however encountered in the PCI practice is one in which a stenotic artery interconnects with other stenotic arteries and it is no longer in an independent stand-alone position since inter-arterial stenosis-stenosis interactions take place. Due to this substantial change of circumstances, treatment decision criteria no longer apply to FFR true of an artery, rather to its actual FFR (denoted FFR real ). The multi-artery FFR method is not intended to constitute a substitute for any of the current FFR-oriented methods. As single-artery FFR-oriented methods cannot resolve complex scenarios of interacting stenotic coronary arteries, in this article the novel multi-artery FFR method extends these methods to the multi-artery domain with no need to alter their associated experimental techniques nor their treatment decision criteria. Reduction of the mathematics to minimal number of simple formulas in this article enables the PCI practitioner to apply the formulas to measured intracoronary pressures in real time.","PeriodicalId":289086,"journal":{"name":"Online Journal of Cardiovascular Research","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131655954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Method: This is a descriptive cross-sectional study. The study sample consisted of 118 patients who had open heart surgery in a cardiovascular surgery clinic of a cardiovascular surgery training hospital. The study was conducted between October and December 2018 in a 3-month period. The mobility difficulties experienced by the patients and their activity levels during the postoperative period were evaluated using the Patient Mobility Scale and the Observer Mobility Scale. The data were analyzed using SPSS 25.0 software. Results: 41.7% of patients returned to the other side of the bed, 36.3% had to sit on the edge of the bed and 32.8% had oral warning and physical help while walking in the room, while 27.4% stand up independently with verbal warning on the edge of the bed. they were able to get up. The results showed that the patients were unable to turn independently from one side of the bed to the other. Conclusion: The findings of this study are significant in order to show that the patients who have undergone open heart surgery to increase the level of movement in early postoperative period will have a positive effect on the overall recovery process of the patients.","PeriodicalId":289086,"journal":{"name":"Online Journal of Cardiovascular Research","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126346246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We searched on the online database “Pubmed” the MESH terms “Hypertension” and “Frail Elderly” and we selected 32 out of 76 papers published in the last 10 years; from this 32 we selected the ones that approached the treatment targets for blood pressure. This research was complemented with the inclusion of other international guidelines and papers that were found relevant. From the papers selected to perform this review, we found guidelines, reviews and observational studies, some with conflicting results and others that are unable to define a blood pressure target in frail and institutionalized elderly. Hypertension is a well stablished cardiovascular (CV) risk factor in adults, active independent older people and even in frail elderly; nevertheless in the group of frail elderly there is evidence that they might lack a benefit in the aggressive treatment of high blood pressure. The randomized controlled trials from Beckett N, et al. [1] and Briasoulis A, et al. [2] showed that the hypertension treatment in older patients (age ≥65 years) and very old patients (≥80 years) significantly reduced CV morbidity and CV and all-cause mortality. In this studies treatment of hypertension was found to be well tolerated. The 2018 ESC/ESH guidelines recommend systolic blood pressure (SBP) target at 130-139 mmHg and diastolic blood pressure (DBP) under 80 mmHg for elderly above 65 years. The American guidelines (2017) recommend SBP under 130 mmHg for community dwelling older people above 65 years, but also recommend wariness in the risk-benefit relation, presence of comorbidities and limited life span. The Canadian guidelines (2018) refer to a lack of evidence to make a recommendation in blood pressure targets in institutionalized elderly [3]. The Australian guidelines (2016) recommend a target of SPB under 120 mmHg and the British (2017) omit a recommendation referring to targets in this population.","PeriodicalId":289086,"journal":{"name":"Online Journal of Cardiovascular Research","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133243341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
