Dyspnea Among Patients With Chronic Total Occlusions Undergoing Percutaneous Coronary Intervention: Prevalence and Predictors of Improvement.

ABSTRACT: BACKGROUND:Dyspnea is a common angina equivalent that adversely affects quality of life, but its prevalence in patients with chronic total occlusions (CTOs) and predictors of its improvement after CTO percutaneous coronary intervention (PCI) are unknown. We examined the prevalence of dyspnea and predictors of its improvement among patients selected for CTO PCI. METHODS AND RESULTS:In the OPEN CTO registry (Outcomes, Patient health status, and Efficiency iN Chronic Total Occlusion) of 12 US experienced centers, 987 patients undergoing CTO PCI (procedure success 82%) were assessed for dyspnea with the Rose Dyspnea Scale at baseline and 1 month after CTO PCI. Rose Dyspnea Scale scores range from 0 to 4 with higher scores indicating more dyspnea with common activities. A total of 800 (81%) reported some dyspnea at baseline with a mean (±SD) Rose Dyspnea Scale of 2.8±1.2. Dyspnea improvement was defined as a ?1 point decrease in Rose Dyspnea Scale from baseline to 1 month. Predictors of dyspnea improvement were examined with a modified Poisson regression model. Patients with dyspnea were more likely to be female, obese, smokers, and to have more comorbidities and angina. Among patients with baseline dyspnea, 70% reported less dyspnea at 1 month after CTO PCI. Successful CTO PCI was associated with more frequent dyspnea improvement than failure, even after adjustment for other clinical variables. Anemia, depression, and lung disease were associated with less dyspnea improvement after PCI. CONCLUSIONS:Dyspnea is a common symptom among patients undergoing CTO PCI and improves significantly with successful PCI. Patients with other potentially noncardiac causes of dyspnea reported less dyspnea improvement after CTO PCI.

Project description:Background: Evidence on factors associated with guideline-directed secondary prevention medication (GDPM) after percutaneous coronary intervention (PCI) and its effect on the prognosis of patients with coronary artery disease (CAD) is lacking in China. Aims: To ascertain predictors of GDPM in real-world clinical practice and to assess the effect of GDPM on clinical outcomes. Design: A retrospective cohort study. Methods: Consecutive patients admitted to Fuwai Hospital between January 2013 and December 2013 were recruited. GDPM comprised aspirin, clopidogrel, statins, β-blockers, and angiotensin-converting enzyme inhibitors/angiotensin Ⅱ receptor blockers. The primary outcome was five-year major adverse cardiovascular event (MACE) (cardiac death, myocardial infarction [MI] and unplanned revascularization). Multivariable logistic regression was used to identify predictors of prescribing GDPM. Multivariable Cox regression was used to examine the relationship between GDPM and clinical outcomes. Results: 10,067 patients were followed up for a median of 5.0 years (interquartile range: 4.3–5.2), 45.1% were prescribed with GDPM. Presenting with ST-segment elevation MI (adjusted OR = 3.252 [2.832–3.736]), prior MI (adjusted OR = 2.174 [1.948–2.425]), more stents implanted (adjusted OR = 1.063 [1.022–1.106]), overweight (adjusted OR = 1.136 [1.038–1.243]), obesity (adjusted OR = 1.274 [1.100–1.476]), diabetes (adjusted OR = 1.225 [1.115–1.344]), and hypertension (adjusted OR = 3.556 [3.196–3.956]) predicted the prescription of GDPM. Advanced age (adjusted OR = 0.556 [0.379–0.816]) was associated with lower prescription rate of GDPM. Patients with GDPM had lower rate of 5-year MACE (adjusted HR = 0.889 [0.808–0.978]) relative to those without GDPM. Conclusions: Despite the benefit of GDPM in improving the prognosis of CAD patients undergoing PCI, gaps still exist in GDPM prescription in real-world clinical practice. Our study determined target populations for physicians to strive to promote the application of GDPM.
