Path analysis for key factors influencing long-term quality of life of patients following a percutaneous coronary intervention

Perceived social support among percutaneous coronary intervention patients over a long-term follow-up period

AIM

To investigate perceived social support and the associated factors as well as the sources of social support among post-percutaneous intervention patients over a long-term follow-up period.

DESIGN

An explanatory and descriptive survey with a six-year follow-up (STROBE Statement: Supplementary file 1).

METHODS

Baseline data (n = 416) were collected from Finnish patients in 2013, with follow-up data collected from the same study group in 2019 (n = 154). The research employed the Social Support of Patients with Coronary Heart Disease self-reported questionnaire. Data were analysed using descriptive statistics and multivariate methods.

RESULTS

In the acute phase, higher informational support was associated with lower LDL cholesterol and female gender and higher emotional support with working status. In long-term follow-up period, physical activity, younger age, normal cholesterol levels and previous percutaneous coronary intervention predicted higher informational support, regular participation in follow-up sessions and relationship status predicted higher emotional support, and previous coronary artery bypass grafting, smoking, alcohol consumption, normal cholesterol and regular follow-ups predicted higher functional support.

Sleep profile and the risk of cardiovascular events in patients undergoing percutaneous coronary intervention

A significant proportion of patients with coronary artery disease (CAD) who undergo percutaneous coronary intervention (PCI) suffer from physical and mental disorders which lead to the decline of sleep profile. Sleep disorders are highly prevalent in these patients. But the effect of sleep on the outcomes of post-PCI patients remains unclear. We aim to examine the individual and joint effects of sleep quality and sleep duration on the risk of adverse cardiovascular events in post-PCI patients. We included 314 participants who were diagnosed with a first CAD and underwent PCI with drug-eluting stents and followed up for a mean duration of 341 days to assess major adverse cardiovascular events (MACEs). Sleep quality, based on the Pittsburgh Sleep Quality Index, was categorized as good (a score of ≤7) or poor (>7). Sleep duration was categorized into three classes: ≤ 5, 6-8 (reference group) and ≥ 9 hours per day. The log-rank test and the Cox regression model were used for data analysis. MACEs occurred in 26 (8.3%) patients. Subjects whose sleep duration was ≤ 5 hours per day had a shorter time to MACEs than those whose sleep duration was 6-8 hours (p = 0.036). A significantly increased risk for MACEs was observed for participants with a ≤ 5 hours sleep duration (HR = 2.18, 95% CI = 1.02-4.64) after adjustment for demographic and clinical confounders. Associations between long sleep duration (≥ 9 hours), sleep quality, or their joint effect and MACEs were not found. This suggests the importance of considering sleep loss when developing strategies to improve health outcomes of PCI patients. And further researches are needed to examine the effects of different aspects of sleep quality on the prognosis of PCI patients and explore the reasons that lead to the decline of sleep profile.

Association between perceived health and adherence to treatment after percutaneous coronary intervention: A long-term follow-up study

AIMS

To identify associations between perceived health and treatment adherence six years after percutaneous coronary intervention.

DESIGN

A non-experimental descriptive long-term follow-up study.

METHODS

Baseline data (n = 416) were collected in 2013, with follow-up data collected in 2019 (n = 154), using the EuroQoL scale, EuroQoL visual analogue scale, and Adherence of Patients with Chronic Disease Instrument. Data were analysed using descriptive statistics and multivariate methods.

RESULTS

The average age of the 154 respondents was 68.5 years (SD 7.01), with a majority males (n = 118, 86.6%). Adherence to a healthy lifestyle, good perceived results of care, support from nurses, high sense of normality, low fear of complications, motivation, older age, and duration of coronary artery disease were associated with better general perceived health as well as its dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression).

CONCLUSION

Support from nurses is a key factor to ensuring high perceived health among post-percutaneous coronary intervention patients. This support must be continuous and motivate the patient to adhere to a healthy lifestyle. Patients should feel comfortable sharing their problems and fears. This type of relationship will allow health care professionals to assess the patient's current situation and address potential problems about mobility, pain and discomfort, as well as anxiety and depression to strengthen the patient's sense of normality and enable them to confidently lead a normal life.

IMPACT

The research aimed to gain knowledge about how perceived health is associated with treatment adherence six years after percutaneous coronary intervention. The results emphasise that a nurse's support of patients is crucial to the care process, as adherence to treatment showed a clear positive association with perceived health in the analysed sample of post-PCI patients.

Health-Related Quality of Life in Patients With Coronary Artery Disease Undergoing Percutaneous Coronary Intervention: A Cross-Sectional Study

BACKGROUND

The percutaneous coronary intervention (PCI) is the most common treatment for coronary artery disease. Health-related quality of life (HRQoL), alongside mortality and recurrence rates, is a key outcome indicator for PCI.

PURPOSE

The aim of this study was to investigate the factors influencing HRQoL in patients with coronary artery disease who had received PCI.

METHODS

A convenience sample from the cardiovascular center of a tertiary hospital in South Korea was recruited for this descriptive, cross-sectional study. This study was conducted using a structured questionnaire and patients' medical records on a sample of 210 patients with coronary artery disease who were ≥ 18 years old and > 1 month post-PCI. The questionnaire collected information on general, clinical, and psychosocial characteristics. Data were analyzed using descriptive statistics, independent t test, one-way analysis of variance, the Scheffé test, and the Pearson correlation test. A multiple linear regression, together with the significant variables in univariate analysis, was used to determine the variables that significantly influenced HRQoL.

RESULTS

HRQoL was found to vary significantly with age, marital status, subjective economic status, primary caregiver, duration since first PCI, New York Heart Association class, anxiety, depression, and social support. The significant general characteristics shown to affect HRQoL in patients who had undergone PCI included age, marital status, and primary caregiver. The significant clinical characteristics shown to affect HRQoL included duration from first PCI and New York Heart Association class. The significant psychosocial characteristics shown to affect HRQoL included anxiety and depression. Primary caregiver and New York Heart Association class were identified as having the greatest impact on HRQoL in the PCI patients in this study.

CONCLUSIONS

To enhance HRQoL in patients who had received PCI, their post-PCI physical and psychological symptoms should be regularly assessed. Furthermore, intervention strategies aimed to improve quality of life in patients with severe functional limitations and those receiving family care are necessary.
