The usefulness of optical coherence tomography in a patient on antiplatelet therapy and requiring surgery

Establishing a balance between the risk of stent thrombosis and the risk of perioperative bleeding in patients treatedwith dual antiplatelet therapy remains a major therapeutic challenge. We report a case of 60-year-old man after stent implantation in left main coronary artery and requiring urgent operative treatment. The result of optical coherence tomography helped us to decide about further proceeding and is an example of a very helpful application of this new imaging technique in everyday practice.Establishing a balance between the risk of stent thrombosis and the risk of perioperative bleeding in patients treatedwith dual antiplatelet therapy remains a major therapeutic challenge.

The use of rotational atherectomy in high-risk patients: results from a high-volume centre

Background: Rotational atherectomy (RA) is indicated for fibrocalcified lesions when traditional percutaneous coronary intervention (PCI) could not be successfully performed. In some of the high-risk patients the RA procedure is the last resort for successful revascularisation. Such patients are, among others, those in whom coronary artery bypass grafting (CABG) is not feasible.Aim: The aim of the study was to assess in-hospital and one-year outcomes of PCI with RA in high-risk patients without other revascularisation options (RA-only group), in comparison to lower-risk patients undergoing RA.Methods: We evaluated data of 207 consecutive patients who underwent PCI with RA. Primary endpoints were one-year all-cause mortality and one-year major adverse cardiac events (MACEs). Secondary endpoints were in-hospital outcomes.Results: During the study 35% of patients fulfilled the inclusion criteria to the high-risk group. Those patients had significantly lower left ventricular ejection fraction, more often prior CABG, higher admission glucose level, and higher EuroSCORE II and Syntax Score. Procedural success was similar in both groups (85% in RA-only group vs. 91% in remaining patients, p = 0.18). In-hospital outcomes were similar, except more frequent no/slow-flow phenomenon in the RA-only group. The MACE and mortality rates in one-year follow-up were not statistically different in both groups (19% vs. 18%, p = 0.82 and 11% vs. 9%, p = 0.64, respectively).Conclusions: Despite the high-risk characteristics of the study subgroup, no significant differences between in-hospital and one-year outcomes were found in comparison to lower-risk RA patients. Complex PCI with RA in patients without other revascularisation options should be taken into consideration

Radial versus femoral access in patients treated with percutaneous coronary intervention and rotational atherectomy

Background: The association between periprocedural complications and the type of vascular access in patients treated with percutaneous coronary intervention (PCI) and rotational atherectomy (RA) has not been investigated as frequently as in an overall group of patients treated with PCI. Aims: The aim of this study was to assess the associations between the type of vascular access and selected periprocedural complications in a group of patients treated with PCI and RA. Methods: ased on a nationwide Polish registry (National Registry of Percutaneous Coronary Interventions [ORPKI]), we analyzed 536 826 patients treated with PCI between the years 2014 and 2018. The study included 2713 patients (0.5% of the overall group of patients treated with PCI [n = 536 826]) treated with PCI and RA. Among them, 1018 (37.5%) were treated via femoral access, and 1653 (60.9%) via radial access. Subsequently, these patients were subject to comparison, which was proceeded by propensity score matching. Results: Following propensity score matching, multiple regression analysis revealed that patients undergoing PCI via femoral access experienced coronary artery perforation significantly less frequently than those managed via radial access (odds ratio, 0.29; 95% CI, 0.08–0.92; P = 0.04). We did not observe any significant associations between the type of vascular access and the periprocedural mortality rate (P = 0.99), cardiac arrest (P = 0.41), puncture‑site bleeding (P = 0.99), allergic reaction (P = 0.32), myocardial infarction (P = 0.48), no‑reflow phenomenon (P = 0.82), or the overall complication rate (P = 0.31). Conclusion: In patients treated with PCI and RA, femoral access is associated with a lower rate of coronary artery perforations as compared with radial access

Digital health and modern technologies applied in patients with heart failure: Can we support patients' psychosocial well-being?

Despite advances in the treatment of heart failure (HF), the physical symptoms and stress of the disease continue to negatively impact patients' health outcomes. Technology now offers promising ways to integrate personalized support from health care professionals via a variety of platforms. Digital health technology solutions using mobile devices or those that allow remote patient monitoring are potentially more cost effective and may replace in-person interaction. Notably, digital health methods may not only improve clinical outcomes but may also improve the psycho-social status of HF patients. Using digital health to address biopsychosocial variables, including elements of the person and their context is valuable when considering chronic illness and HF in particular, given the multiple, cross-level factors affecting chronic illness clinical management needed for HF self-care

Could an analysis of mean corpuscular volume help to improve risk stratification in non-anemic patients with acute myocardial infarction?

Background: Nowadays, when the majority of patients with acute myocardial infarction (AMI) are treated with primary percutaneous coronary intervention and modern pharmacotherapy, risk stratification becomes a challenge. Simple and easily accessible parameters that would help in a better determination of prognosis are needed. The aim of the study was to estimate the prevalence of high mean corpuscular volume (MCV, defined as MCV > 92 fL) and to establish its prognostic value in non-anemic patients with AMI. Methods: We retrospectively analyzed the data of 248 consecutive non-anemic patients hospitalized due to AMI (median age: 65 [59–76] years, men: 63%, ST segment elevation myocardial infarction: 31%, and median left ventricular ejection fraction [LVEF]: 50%). Results: The prevalence of high MCV was 39 ± 6% (± 95% confidence interval) in the entire AMI population. High MCV was more prevalent in males, patients with low body mass index, non-diabetics and cigarette smokers (all p < 0.05). During the 180-day follow-up, there were 38 (15%) events, defined as another AMI or death. In a multivariable Cox proportional hazard model, female gender (p < 0.01), low LVEF (p < 0.001), previous AMI (p < 0.05), arterial hypertension (p < 0.05), and high MCV (p < 0.001) were prognosticators of pre-defined events. Conclusions: In non-anemic patients with AMI, high MCV is an independent prognostic factor of poor outcome defined as another AMI or death.
