Study on the safety and effectiveness of drug-coated balloons in patients with acute myocardial infarction

Abstract background Drug-coated balloon (DCB) is a new technology that has emerged in recent years and has been proven to be effective and safe in the treatment of in-stent restenosis. The purpose of this article is to observe the safety and effectiveness of drug-coated balloons in patients with acute myocardial infarction. method We selected 80 patients admitted to the hospital for STEMI from January 2018 to December 2019. The subjects were randomly divided into a Yinyi (Liaoning) Biotech Bingo Drug Coated Balloon treatment group (balloon group, n = 38) and a drug-eluting stent (DES) treatment group (stent group, n = 42). Patients were followed up to understand the incidence of major adverse cardiovascular events (MACE) at 1 month, 6 months and 1 year after surgery. Coronary angiography was rechecked 1 year after surgery to understand the late lumen loss (LLL) in the two groups. result During the one-year follow-up, the LLL of the target lesion in the balloon group was -0.12±0.46 mm, while the target lesion in the stent group was 0.14±0.37 mm ( P <0.05). Within 1 year, the incidence of MACE in the balloon group was 11%, while the incidence of MACE in the stent group was 12%. There was no significant difference between the two groups. in conclusion When PCI is used for STEMI, only DCB therapy is safe and effective, and has shown good clinical effects during a one-year follow-up period.

Abstract Background：Drug-coated balloon (DCB) is a new technology that has emerged in recent years, and it has been proven to be effective and safe in the treatment of restenosis in the stent. The purpose of this article is to observe the safety and effectiveness of drug-coated balloons in patients with acute myocardial infarction. Methods: A total of 80 patients who were admitted to our department due to STEMI from January 2018 to December 2019 were selected. The subjects were randomly divided into drug-coated balloon treatment group (balloon group, n=38) and drug-eluting stent (DES) treatment group (stent group, n=42). The patients were followed up for 1 year to understand the incidence of major adverse cardiovascular events (MACEs) at 1 month, 6 months and 1 year after operation. Coronary angiography was reexamined at 1 year after operation to understand the late lumen loss (LLL) of the two groups. Results: At the 1-year follow-up, the target lesion LLL in the balloon group was (−0.12±0.46) mm, while the target lesion in the stent group was (0.14±0.37) mm (P<0.05). Within 1 year, the incidence of MACEs in the balloon group was 11%, and the incidence of MACEs in the stent group was 12%. There was no significant difference between the two groups. Conclusion: DCB therapy alone is safe and effective when PCI is performed for STEMI, and it shows good clinical results during the 1-year follow-up period.

Background. Limited data are available to support an invasive treatment strategy in nonagenarians with acute myocardial infarction (AMI). We aimed to investigate whether percutaneous coronary intervention (PCI) is beneficial in this frail population. Methods. We retrospectively analyzed 41 nonagenarians with AMI (both ST-segment-elevation and non-ST-segment-elevation MI) between 2006 and 2015 in a single center. We assessed 30-day and one-year mortality rates according to the treatment strategy. Results. Among study subjects, 24 (59%) were treated with PCI (PCI group) and 17 (41%) were treated with conservative management (medical treatment group) per the clinician’s discretion. The median follow-up duration was 30 months (0–74 months). Thirty-day mortality was lower in the PCI group than in the medical treatment group (17% vs. 65%; P < 0.001 ). One-year mortality was also lower in the PCI group than in the medical treatment group (21% vs. 76%; P < 0.001 ). The PCI group presented a 73% decreased risk of death (adjusted hazard ratio: 0.269; 95% confidence interval: 0.126–0.571; P < 0.001 ). In the Killip class 1 through 3 subgroups (n = 36), 30-day and one-year mortality were still higher among those in the medical treatment group (13% vs. 54% at 30 days; P < 0.001 and 17% vs. 69% at one year; P < 0.001 ). Landmark analysis after 30 days revealed no significant difference in the cumulative mortality rate between the two groups, indicating that the mortality difference was mainly determined within the first 30 days after AMI. Conclusion. Mortality after AMI was decreased in correlation with the invasive strategy relative to the conservative strategy, even in nonagenarians. Regardless of age, PCI should be considered in AMI patients. However, large-scale randomized controlled trials are needed to support our conclusion.

Abstract Funding Acknowledgements Type of funding sources: Public Institution(s). Main funding source(s): National Health Fund Background. A novel comprehensive care program after acute myocardial infarction (AMI) „KOS-zawał" was implemented in Poland. It includes acute intervention, complex revascularization, implantation of cardiovascular electronic devices (in case of indications), rehabilitation or hybrid telerehabilitation (HTR) and scheduled outpatient follow-up. HTR is a unique component of this program. The purpose of the pilot study was to evaluate a feasibility, safety and patients’ acceptance of HTR as component of a novel care program after AMI and to assess mortality in a one-year follow-up. Methods The study included 55 patients (LVEF 55.6 ± 6.8%; aged 57.5 ± 10.5 years). Patients underwent a 5-week HTR based on Nordic walking, consisting of an initial stage (1 week) conducted within an outpatient center and a basic stage (4-week) home-based telerehabilitation five times weekly. HTR was telemonitored with a device adjusted to register electrocardiogram (ECG) recording and to transmit data via mobile phone network to the monitoring center. The moments of automatic ECG registration were pre-set and coordinated with exercise training. The influence on physical capacity was assessed by comparing changes in functional capacity (METs) from the beginning and the end of HTR. Patients filled in a questionnaire in order to assess their acceptance of HTR at the end of telerehabilitation. Results HTR resulted in a significant improvement in functional capacity and workload duration in exercise test (Table). Safety: there were neither deaths nor adverse events during HTR. Patients accepted HTR, including the need for interactive everyday collaboration with the monitoring center. Prognosis all patients survived in a one-year follow-up. Conclusions Hybrid telerehabilitation is a feasible, safe form of rehabilitation, well accepted by patients. There were no deaths in a one-year follow-up.

Abstract Background Malignant arrhythmias, ventricular tachycardia or ventricular fibrillation (VT/VF) in acute myocardial infarction (AIM) carry ominous prognosis including sudden cardiac death (SCD). It is not clear whether the timing of VT/VF occurrence always affects the poor prognosis of patients with AMI. Aim To investigate the prognosis of patients who undergoing primary percutaneous coronary intervention (PCI) in accordance with timing of VT/VF and to find the power predictors of their occurrence. Methods 307 consecutive patients in PREDICT-VT study (NCT03263949), 57.9±10.6 year old, 72.3% males were analysed. Of these patients, 27.7% had VT/VF from the symptoms onset, within 48 hours of AIM (early VT/VF group). 8.1% of patients had VT/VF after 48h, during one year follow up (late VT/VF group). Results The frequency of VT/VF occurrence was high between symptoms onset and the end of 2nd month and during 5th and 6th month of AIM. The parameters of conventional echocardiography were significantly impaired in late VT/VF group, as well as parameters of longitudinal strain (LS) (table). Moreover, the MACE (cardiovascular mortality, SCD, new infarction, emergency revascularisation, and hospitalized heart failure) was the highest in late VT/VF group (p=0.000). The most significant predictor of late VT/VF was systolic LS (cut off −12.72%, ROC 0.680, Sen 71%, Sp 64%, p=0.006). Conclusions Although late VT/VF occurrence after primary PCI were less frequent than early VT/VF occurrence, patients with late VT/VF had a very poor prognosis. The most power predictor of late VT/VF were systolic longitudinal strain. Funding Acknowledgement Type of funding source: Public hospital(s). Main funding source(s): Clinical Center of Serbia

Objective. The pathophysiologic mechanism of how thyroid function is related to the development and prognosis of acute myocardial infarction (AMI) remains under explored, and there has been a lack of clinical investigations. In this study, we investigate the relationship between triiodothyronine (T3) level and cardiac ejection fraction (EF) as well as probrain natriuretic peptide (NT-proBNP) on admission and subsequent prognosis in AMI patients. Methods. We measured admission thyroid function, NT-proBNP, and EF by echocardiography in 345 patients diagnosed with AMI. Simple and multiregression analyses were performed to investigate the correlation between T3 level and EF as well as NT-proBNP. Major adverse cardiovascular events (MACE), including new-onset myocardial infarction, acute heart failure, and cardiac death, were documented during the follow-up. 248 participants were separated into three groups based on T3 and free triiodothyronine (FT3) levels for survival analysis during a 2-year follow-up. Results. 345 patients diagnosed with AMI were included in the initial observational analysis. 248 AMI patients were included in the follow-up survival analysis. The T3 levels were found to be significantly positively correlated with EF (R square=0.042, P<0.001) and negatively correlated with admission NT-proBNP levels (R square=0.059, P<0.001), which is the same with the correlation between FT3 and EF (R square=0.053, P<0.001) and admission NT-proBNP levels (R square=0.108, P<0.001). Kaplan-Meier survival analysis revealed no significant difference with regard to different T3 or FT3 levels at the end of follow-up. Conclusions. T3 and FT3 levels are moderately positively correlated with cardiac function on admission in AMI patients but did not predict a long-time survival rate. Further studies are needed to explain whether longer-term follow-up would further identify the prognosis effect of T3 on MACE and all-cause mortality.
