Fibrinogen is an independent preoperative predictor of hospital length of stay among patients undergoing coronary artery bypass grafting

OBJECTIVE

This study aims to examine the impact of preoperative fibrinogen concentration on the short-term outcomes and hospital length of stay (LOS) of patients undergoing Coronary Artery Bypass Grafting (CABG).

METHODS

Between January 2010 and June 2022, a retrospective analysis comprised 633 patients who sequentially received isolated, primary CABG. These patients were categorized into normal fibrinogen group (fibrinogen < 3.5 g/L) and high fibrinogen group (fibrinogen ≥ 3.5 g/L) according to preoperative fibrinogen concentration. The primary outcome was LOS. To correct for confounding and investigate the effect of preoperative fibrinogen concentration on the short-term outcomes and LOS, we employed propensity score matching (PSM). The correlation between fibriongen concentration and LOS in subgroups was examined using subgroup analysis.

RESULTS

We categorized 344 and 289 patients in the "normal fibrinogen group" and "high fibrinogen group", respectively. After PSM, compared to the normal fibrinogen group, the high fibrinogen group had a longer LOS [12.00 (9.00-15.00) vs. 13.00 (10.00-16.00), P = 0.028] and higher incidence of postoperative renal impairment [49 (22.1%) vs. 72 (32.4%), P = 0.014]. Cardiopulmonary bypass (CPB) or non-CPB CABG patients showed similar correlations between various fibrinogen concentrations and LOS, according to subgroup analyses.

CONCLUSIONS

Fibrinogen is an independent preoperative predictor of both the LOS and the postoperative renal impairment that occurs after CABG. Patients with high preoperative fibrinogen concentration had a higher incidence of postoperative renal impairment and a longer LOS, emphasizing the significance of preoperative fibrinogen management.

Quality of Life and Social Functioning of Patients After Cardiosurgical Interventions

The objective: to study the quality of life (QOL) and social functioning of patients who underwent cardiosurgery intervention (CSI) with the use of artificial circulation (AR) in the postoperative period, to determine and improve the system for further medical, psychological and social rehabilitation. Materials and methods. 700 patients who underwent CSI with the use of AR were treated at the Heart Institute of the Ministry of Health of Ukraine. 86 patients had cerebral infarction (CI), 217 patients with signs of postoperative encephalopathy, and 504 patients with signs of cognitive dysfunction. The level of QOL and social functioning in patients with this pathology was analyzed. Statistical analysis of differences in the quantitative values of indicators was performed using the nonparametric Mann-Whitney test. Results. It was found that patients after CSI had generally low levels of QOL in all fields, namely in the indicators of psychological (emotional) well-being, general perception of life, ability to work, physical well-being, personal realization, selfcare and independence; interpersonal interaction. The presence of ischemic and neurological complications in patients after CSI significantly reduces the QOL indicators in all areas, with differences in the quantitative values of such patients statistically significant (p<0,01) compared to the groups of patients without such complications. The most significant deterioration of QOL is found in patients with cerebral infarction in the postoperative period, slightly less significant – in patients with signs of postoperative encephalopathy, and the smallest changes – in patients with signs of cognitive dysfunction. Conclusions. The main task of modern cardiac surgery is not only to save the patient from death, but also to improve the quality of life (QOL). At the same time, patients after cardiac surgery are at risk of developing ischemic, neurological complications that significantly reduce QOL in all areas of life. That is why it is necessary to take into account the findings of the study in the development of treatment and rehabilitation programs and preventive measures for such patients.

Quality of life in patients with stable coronary artery disease submitted to percutaneous, surgical, and medical therapies: a cohort study

Background

Clinical, surgical, and percutaneous strategies similarly prevent major cardiovascular events in patients with stable coronary artery disease (CAD). The possibility that these strategies have differential effects on health-related quality of life (HRQoL) has been debated, particularly in patients treated outside clinical trials.

Methods

We assigned 454 patients diagnosed with CAD during an elective diagnostic coronary angiography to coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), or optimal medical treatment (OMT), and followed them for an average of 5.2 ± 1.5 years. HRQoL was assessed using a validated Brazilian version of the 12-Item Short-Form Health Survey questionnaire. The association between therapeutic strategies and quality of life scores was tested using variance analysis and adjusted for confounders in a general linear model.

Results

There were no differences in the mental component summary scores in the follow-up evaluation by therapeutic strategies: 51.4, 53.7, and 52.3 for OMT, PCI, and CABG, respectively. Physical component summary scores were higher in the PCI group than the CABG and OMT groups (46.4 vs. 42.9 and 43.8, respectively); however, these differences were no longer different after adjustment for confounding variables.

Conclusion

In a long-term follow-up of patients with stable CAD, HRQoL did not differ in patients treated by medical, percutaneous, or surgical treatments.

Unrestricted use of polymer-free sirolimus eluting stents in routine clinical practice

Stent designs with ultrathin struts may further increase the procedural success of challenging lesion subsets. The objective of this study was to assess the safety and efficacy of ultrathin strut, polymer-free sirolimus eluting stent (PF-SES) implantations in a large scale, unselected patient population.Adult patients underwent percutaneous coronary interventions (PCI) with a thin-strut PF-SES. Data from two all-comers observational studies having the same protocol (ClinicalTrials.gov Identifiers: NCT02629575 and NCT02905214) were pooled. The accumulated target lesion revascularization (TLR) rate at 9-12 months was the primary endpoint. All dual antiplatelet therapy strategies according to the applicable guidelines were permissible.In total, 7243 patients were prospectively enrolled for PCI with PF-SES in stable coronary artery disease or acute coronary syndrome (ACS). Major risk factors in the overall cohort were diabetes (37.3%), ST elevation myocardial infarction (18.1%) and non-ST myocardial infarction (24.6%). The follow-up rate was 88.6% in the overall population. The TLR rate in the overall cohort was 2.2% whereas definite/probable stent thrombosis (ST) occurred in 0.7%. In patients with in-stent restenosis lesions, the major adverse cardiac events rate was 6.4% whereas the corresponding rate for isolated left main coronary artery (LMCA) disease was highest with 6.7% followed by patients with culprit lesions in vein bypasses (VB, 7.1%). The mortality rate in patients treated in VB lesions was highest with 5.4%, followed by the isolated LMCA subgroup (3.4%) and ACS (2.6%).PCI with PF-SES in an unselected patient population, is associated with low clinical event and ST rates. Furthermore, PF-SES angioplasty in niche indications demonstrated favorable safety and efficacy outcomes with high procedural success rates.
