Transradial percutaneous coronary intervention for acute myocardial infarction reduces CCU stay in patients 80 or older

Relationship Between Coronary Artery Revascularization and Postoperative Delirium: Progress and Perspectives

Brain dysfunction resulting from damage to the heart-brain link leads to a decline in cognitive function. This, in turn, gives rise to the clinical symptom of perioperative delirium in patients undergoing coronary artery revascularization. Those affected are provided symptomatic treatment, but many do not recover fully. Thus, medium- and long-term mortality and adverse event rates remain relatively high in patients with perioperative delirium. Despite the relatively high incidence of perioperative delirium in patients undergoing coronary artery revascularization, it has not been systematically investigated. Inflammation, vascular damage, neuronal damage, and embolism are all involved in the injury process. Here, we discuss the incidence rate, pathological mechanisms, and prognosis of delirium after coronary artery revascularization. We also discuss in detail the risk factors for delirium after coronary artery revascularization, such as anxiety, depression, mode of operation, and drug use. We hope that prevention, early diagnosis, assessment, and potential treatment can be achieved by cardiologists to improve patient prognosis.

Age, preoperative higher serum cortisol levels, and lower serum acetylcholine levels predict delirium after percutaneous coronary intervention in acute coronary syndrome patients accompanied with renal dysfunction

BACKGROUND

The objective of the study is to investigate the incidence and risk factors of delirium after percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) patients accompanied with renal dysfunction.

MATERIALS AND METHODS

This was a prospective and cohort study, performed in a medical center from July 2014 to June 2017, which enrolled ACS patients accompanied with renal dysfunction who were treated with PCI. Univariate analysis and binary logistic regression analysis was used to determine the incidence and risk factors of delirium.

RESULTS

Data were analyzed from 119 patients. The 7-day incidence of delirium after PCI in ACS patients accompanied with renal dysfunction was 15.97% (n = 19/119). The binary logistic regression analysis results indicate that age (odd ratio [OR] 1.463; 95% confidence interval [CI] 1.070-2.001; P = 0.017), preoperative higher serum cortisol (COR) (OR 1.025; 95% CI 1.002-1.048; P = 0.030), and lower serum acetylcholine (Ach) (OR 0.965; 95% CI 0.937-0.993; P = 0.016) were significant differences in delirium and nondelirium groups.

CONCLUSIONS

Age, preoperative higher serum COR levels, and lower serum Ach levels were independent risk factors for delirium after PCI in ACS patients accompanied with renal dysfunction.

[Radial approach in the elderly]

Due to the steady increase in life expectancy, the number of patients over 80 years of age proposed for coronary angioplasty is increasing significantly. The elderly patient is a patient at high cardiovascular risk and high risk of bleeding; whose severity of prognosis depends of comorbidities. The radial approach presents particularities and technical difficulties that have to be known in this part of the population, but reduce vascular and hemorrhagic complications, as well as mortality. Because of greater safety, the radial approach is therefore the first choice for the elderly.

Clinical outcomes after acute myocardial infarction according to a novel stratification system linked to a rehabilitation program

BACKGROUND

A risk classification of acute myocardial infarction (AMI) linked to a rehabilitation program has not been established.

METHODS

We allocated 292 patients with AMI into the low- (L) (n=108), intermediate- (I) (n=72), and high- (H) (n=112) risk groups according to our original risk classification. The primary endpoint was major adverse cardiac events (MACE), defined as the composite of cardiac death, non-fatal AMI, stent thrombosis, and ischemia-driven target vessel revascularization. The mean follow-up period was 252 days.

RESULTS

The length of coronary care unit (CCU) stay and hospital stay was shortest in the L-risk group (CCU stay, 1.0±1.0 days; hospital stay, 5.6±3.2 days), followed by the I-risk group (CCU stay, 2.3±1.8 days; hospital stay, 8.1±2.7 days), and longest in the H-risk group (CCU stay, 5.1±5.0 days; hospital stay, 14.6±12.6 days) (p<0.001). MACE were most frequently observed in the H-risk group (26.8%), followed by the I-risk group (5.6%), and least in the L-risk group (1.9%) (p<0.001).

CONCLUSIONS

The lengths of hospital stay and CCU stay were significantly shortest in the L-risk group, followed by the I-risk group, and longest in the H-risk group. MACE were most frequently observed in the H-risk group, followed by the I-risk group, and least in the L-risk group. These results support the validity of our new classification system.
