we aimed to assess the effect of nutritional nursing intervention on patients with acute ST-segment elevation myocardial infarction (STEMI) accompanied by iron deficiency. this study comprised a prospective observational cohort phase and a nested randomized controlled trial (RCT) phase. In the prospective study phase, 200 patients with a first acute STEMI were consecutively enrolled, of whom 92 were subsequently diagnosed with iron deficiency. In the RCT phase, 90 patients were randomly assigned to conventional nursing, medical-therapy, or nursing intervention group for 12 weeks, with follow-up for six months. after 12 weeks of intervention, the nursing intervention group had significantly higher scores on the eight-item Morisky Medication Adherence Scale than those of medical-therapy and conventional nursing groups (7.3 ± 0.8 vs 6.2 ± 1.0 vs 5.8 ± 1.1, p < 0.001). During the six-month follow-up, the rate of readmission for heart failure was significantly lower in the nursing intervention group than in medical-therapy and conventional nursing groups (6.7 % vs 23.3 % vs 26.7 %). Logistic regression analysis revealed that the risk of readmission reduced (odds ratio = 0.17, 95 % confidence interval: 0.03-0.85, p = 0.031). The left ventricular ejection fraction of the nursing intervention group improved the most (Δ = 7.4 %, p < 0.001), and the improvements in Six Minute Walk Distance (6MWD) test and Kansas City Cardiovascular Questionnaire (KCCQ) scores were
Abstract
we aimed to assess the effect of nutritional nursing intervention on patients with acute ST-segment elevation myocardial infarction (STEMI) accompanied by iron deficiency. this study comprised a prospective observational cohort phase and a nested randomized controlled trial (RCT) phase. In the prospective study phase, 200 patients with a first acute STEMI were consecutively enrolled, of whom 92 were subsequently diagnosed with iron deficiency. In the RCT phase, 90 patients were randomly assigned to conventional nursing, medical-therapy, or nursing intervention group for 12 weeks, with follow-up for six months. after 12 weeks of intervention, the nursing intervention group had significantly higher scores on the eight-item Morisky Medication Adherence Scale than those of medical-therapy and conventional nursing groups (7.3 ± 0.8 vs 6.2 ± 1.0 vs 5.8 ± 1.1, p < 0.001). During the six-month follow-up, the rate of readmission for heart failure was significantly lower in the nursing intervention group than in medical-therapy and conventional nursing groups (6.7 % vs 23.3 % vs 26.7 %). Logistic regression analysis revealed that the risk of readmission reduced (odds ratio = 0.17, 95 % confidence interval: 0.03-0.85, p = 0.031). The left ventricular ejection fraction of the nursing intervention group improved the most (Δ = 7.4 %, p < 0.001), and the improvements in Six Minute Walk Distance (6MWD) test and Kansas City Cardiovascular Questionnaire (KCCQ) scores were also significantly higher than those in the other two groups (p < 0.001). nutritional nursing intervention effectively improved patients' medication compliance, reduced the risk of re-hospitalization for heart failure, and improved their quality of life.
