RESUMO

Hypertension (HTN) management continues to be a concern due to challenges with behavioral risk factors. Patient education to modify unhealthy behaviors appears to be effective in managing HTN. Therefore, this meta-analysis aimed to determine whether individualized face-to-face education and counseling have a beneficial effect on systolic and diastolic blood pressure (SBP and DBP) in hypertensive patients. Studies were extracted from PubMed, Scopus, Cochrane Library, and Web of Science databases. Nine studies, comprising 2627 participants, were included. Random effects models were used to pool estimates of mean differences (MDs) with 95% confidence intervals (CIs) in SBP and DBP between the intervention and usual care groups. SBP and DBP were significantly reduced at the 6-month (MD = -4.38 mmHg, 95% CI: -6.95 to -1.81; MD = -2.09 mmHg, 95% CI: -3.69 to -0.50, respectively) and 12-month time points (MD = -2.48 mmHg, 95% CI: -3.96 to -1.01; MD = -1.71 mmHg, 95% CI: -2.88 to -0.55, respectively) with intervention. At the 24-month time point, there was a significant change in SBP (MD = -2.13 mmHg, 95% CI: -3.94 to -0.32) with intervention compared with the usual care group. This study showed that individualized face-to-face education and counseling add significant benefits to usual care for lowering blood pressure in hypertensive patients. Graphical Abstract.

RESUMO

OBJECTIVE: To determine whether primary percutaneous coronary intervention (PPCI) is associated with adverse outcomes following coronary artery bypass graft (CABG) among patients with ST-elevation myocardial infarction (STEMI). METHODS: Patients presenting with acute STEMI who underwent CABG between September 2015 and November 2020 were included. Among 354 patients, 222 (62.7%) underwent PPCI prior to CABG (PPCI+CABG group) and were compared with the rest of the patients (CABG only group). The effects of PPCI on primary endpoints---including in-hospital mortality, length of stay (LOS), and bleeding events---were investigated using the stabilised inverse probability weighting method (S-IPW). Further, in-hospital mortality in various PPCI subgroups was analysed using univariable regression. RESULTS: Patients with and without PPCI were comparable regarding their baseline and surgical characteristics, except that those without PPCI were more likely to have left-main disease (29.5% vs 16.2%, p-value=0.003). Among the PPCI+CABG group, 3.6% mortality and 55.9% bleeding events occurred, and the LOS was 7 [5-10] days. The respective figures for the CABG only group were 4.5%, 50.8%, and 7 [6-10.5] days. Primary percutaneous coronary intervention, as a whole, was not significantly associated with either morality (S-IPW odds ratio (S-IPW OR) 0.61; p=0.393), LOS logarithm (S-IPW ß -0.050; p=0.403), or bleeding events (S-IPW OR 1.06; p=0.821). Nevertheless, the unadjusted mortality risk was significantly higher in complicated PPCIs compared with the CABG only group (OR 7.50, 95% CI 2.03-27.77); it was also higher among some other PPCI subgroups, albeit non-significantly. CONCLUSION: This study found that PPCI did not confer additional risk regarding in-hospital mortality, LOS, or bleeding among patients with acute STEMI who underwent CABG. However, some PPCI subgroups, especially those with complicated PPCI, were at increased risk.

RESUMO

BACKGROUND: Coronary artery disease (CAD) is a universal public health challenge, more prominently so in the low- and middle-income countries. In this study, we aimed to determine prevalence and trends of CAD risk factors in patients with documented CAD and to determine their effects on the age of CAD diagnosis. MATERIALS AND METHODS: We conducted a registry-based, serial cross-sectional study using the coronary angiography data bank of the Tehran Heart Center. Adult patients who had obstructive (> 50% stenosis) CAD were included in the study. The prevalence and 11-year trends of conventional CAD risk factors were analyzed by sex and age, and their adjusted effects on the age of CAD diagnosis were calculated. RESULTS: From January 2005 to December 2015, data for 90,094 patients were included in this analysis. A total of 61,684 (68.5%) were men and 28,410 (31.5%) were women. Men were younger at diagnosis than women, with a mean age of 60.1 in men and 63.2 in women (p < 0.001), and had fewer risk factors at the time of diagnosis. Mean age at diagnosis had an overall increasing trend during the study period. Increasing trend was seen in body-mass index, hypertension prevalence, diabetes mellitus. All lipid profile components (total cholesterol, low-density lipoprotein cholesterol, triglycerides, and high-density lipoprotein cholesterol) decreased over time. Of particular interest, opium consumption was associated with 2.2 year earlier age of CAD diagnosis. CONCLUSION: The major results of this study (lower age of CAD diagnosis in men, lower age of diagnosis associated with most risk factors, and lower prevalence of serum lipids over time) were expected. A prominent finding of this study is confirming opium use was associated with a much younger age of CAD onset, even after adjusting for all other risk factors. In addition to recommendations for control of the traditional risk factors, spreading information about the potential adverse effect of opium use, which has only recently been associated with higher risk of CAD, may be necessary.

RESUMO

Introduction: Chronic depression and anxiety can be a risk factor for coronary aArtery bypass grafting (CABG) and is an emerging factor after coronary artery disease when the patient is admitted to the hospital and after surgery. We aimed to assess the effect of Escitalopram in treating mild to moderate depressive disorder and improving the quality of life in patients undergoing CABG. Methods: In this randomized clinical trial, 50 patients undergoing CABG referred to Tehran Heart Hospital from January 2021 to May 2021 and were suffering from mild to moderate depression were randomly assigned to one of the two groups of Escitalopram or placebo. The level of depression was assessed based on Beck's depression inventory and the quality-of-life status and its domains were assessed based on the SF-36 questionnaire in 2 groups. Measurements were obtained at baseline and at four and eight weeks after treatment. Chi-square, Fisher's exact, paired, and Wilcoxon tests or ANOVA were used as appropriate. Results: There was no significant difference between the level of depression between the two study groups at baseline (P=0.312). There was no significant difference between the quality of life and its domains in the two study groups at baseline (P=0.607). However, the most important effect of Escitalopram was reducing depression scores in the intervention group at weeks 4 and 8 after treatment compared to the placebo group (P<0.001). The quality of life and its domains were significantly higher in the Escitalopram group eight weeks after treatment (P=0.004). The amount of drug side effects at 2 and 4 weeks after treatment had no significant difference between the groups (P>0.05). Conclusion: Escitalopram was effective in treating mild to moderate depressive disorder and improving quality of life in patients undergoing CABG.

RESUMO

BACKGROUND: Acute kidney injury (AKI) is one of the preventable complications of percutaneous coronary intervention (PCI). This study aimed to develop machine learning (ML) models to predict AKI after PCI in patients with acute coronary syndrome (ACS). METHODS: This study was conducted at Tehran Heart Center from 2015 to 2020. Several variables were used to design five ML models: Naïve Bayes (NB), Logistic Regression (LR), CatBoost (CB), Multi-layer Perception (MLP), and Random Forest (RF). Feature importance was evaluated with the RF model, CB model, and LR coefficients while SHAP beeswarm plots based on the CB model were also used for deriving the importance of variables in the population using pre-procedural variables and all variables. Sensitivity, specificity, and the area under the receiver operating characteristics curve (ROC-AUC) were used as the evaluation measures. RESULTS: A total of 4592 patients were included, and 646 (14.1%) experienced AKI. The train data consisted of 3672 and the test data included 920 cases. The patient population had a mean age of 65.6 ± 11.2 years and 73.1% male predominance. Notably, left ventricular ejection fraction (LVEF) and fasting plasma glucose (FPG) had the highest feature importance when training the RF model on only pre-procedural features. SHAP plots for all features demonstrated LVEF and age as the top features. With pre-procedural variables only, CB had the highest AUC for the prediction of AKI (AUC 0.755, 95% CI 0.713 to 0.797), while RF had the highest sensitivity (75.9%) and MLP had the highest specificity (64.35%). However, when considering pre-procedural, procedural, and post-procedural features, RF outperformed other models (AUC: 0.775). In this analysis, CB achieved the highest sensitivity (82.95%) and NB had the highest specificity (82.93%). CONCLUSION: Our analyses showed that ML models can predict AKI with acceptable performance. This has potential clinical utility for assessing the individualized risk of AKI in ACS patients undergoing PCI. Additionally, the identified features in the models may aid in mitigating these risk factors.

RESUMO

Background: Coronary artery disease (CAD) is the leading cause of cardiovascular death globally, and the most severe form of CAD, ST-elevation myocardial infarction (STEMI), needs immediate treatment. This study aimed to report patient characteristics and the causes of door-to-balloon time (D2BT) delays in STEMI patients admitted to Tehran Heart Center with a D2BT exceeding 90 minutes. Methods: This cross-sectional study was conducted at Tehran Heart Center, Iran, from March 20th, 2020, through March 20th, 2022. Variables consisted of age, sex, diabetes mellitus, hypertension, dyslipidemia, smoking, opium, family history of CAD, in-hospital mortality, primary percutaneous coronary intervention results, culprit vessels, causes of delays, the ejection fraction, triglycerides, and low and high-density lipoprotein levels. Results: The study population was composed of 363 patients (272 males [74.9]) at a mean (SD) age of 60±11.47 years. The leading causes of D2BT delays were the catheterization lab used in 95 patients (26.2) and misdiagnosis in 90 (24.8). Other causes were ST-elevation less than 2 mm in electrocardiograms in 50 patients (13.8) and referral from other hospitals in 40 (11.0). Conclusion: The catheterization lab in use and misdiagnosis were the leading causes of D2BT delays. We recommend that high-volume centers allocate an additional catheterization lab with an on-call cardiologist. Improved resident training and supervision in hospitals with many residents are also necessary.

RESUMO

Aim: A considerable proportion of patients admitted with acute coronary syndrome (ACS) have no standard modifiable cardiovascular risk factors (SMuRFs: hypertension, diabetes mellitus, dyslipidemia, and cigarette smoking). The outcomes of this population following percutaneous coronary intervention (PCI) are debated. Further, sex differences within this population have yet to be established. Methods: This retrospective cohort study included 7,847 patients with ACS who underwent PCI. The study outcomes were in-hospital mortality, all-cause mortality, and major adverse cardio-cerebrovascular events (MACCE). The association between the absence of SMuRFs (SMuRF-less status) and outcomes among all the patients and each sex was assessed using logistic and Cox proportional hazard regressions. Results: Approximately 11% of the study population had none of the SMuRFs. During 12.13 [11.99-12.36] months of follow-up, in-hospital mortality (adjusted-odds ratio (OR):1.51, 95%confidence interval (CI): 0.91-2.65, P:0.108), all-cause mortality [adjusted-hazard ratio (HR): 1.01, 95%CI: 0.88-1.46, P: 0.731], and MACCE (adjusted-HR: 0.93, 95%CI:0.81-1.12, P: 0.412) did not differ between patients with and without SMuRFs. Sex-stratified analyses recapitulated similar outcomes between SMuRF+ and SMuRF-less men. In contrast, SMuRF-less women had significantly higher in-hospital (adjusted-OR: 3.28, 95%CI: 1.92-6.21, P < 0.001) and all-cause mortality (adjusted-HR:1.41, 95%CI: 1.02-3.21, P: 0.008) than SMuRF+ women. Conclusions: Almost one in 10 patients with ACS who underwent PCI had no SMuRFs. The absence of SMuRFs did not confer any benefit in terms of in-hospital mortality, one-year mortality, and MACCE. Even worse, SMuRF-less women paradoxically had an excessive risk of in-hospital and one-year mortality.

RESUMO

BACKGROUND: Octogenarians (age≥80 years) with coronary artery disease constitute a high-risk group and the elderly undergoing percutaneous coronary intervention (PCI) are at higher risk of adverse outcomes compared to young patients. In this study, we aimed to describe the outcomes of the elderly with acute coronary syndrome (ACS) who underwent PCI and also to identify the predictors of short-term major adverse cerebrocardiovascular events (MACCE) in octogenarians. METHODS: In this registry-based cohort study, we reviewed the data of patients (aged≥65 years) who underwent PCI. Univariate Cox-regression model was used to assess the univariate effects of covariates on mortality and MACCE and multivariate Cox-regression analysis were used to discover MACCE predictors. RESULTS: We reviewed the data of 3332 patients (2722 elderly [65 to 79 years], and 610 octogenarians [≥80 years]). The cumulative hazard of MACCE was significantly higher in the octogenarian group compared with the younger group (P<0.001). MACCE in octogenarians presenting with ST-elevation myocardial infarction (STEMI) was significantly higher than those with non-ST-elevation myocardial infarction/Unstable angina (NSTEMI/UA) (P<0.001); however, the cumulative hazard of mortality was not significantly different between the two groups (P=0.270). Successful PCI, left main stenosis and estimated glomerular filtration rate (eGFR) were independent predictors of MACCE in octogenarians with ACS. CONCLUSION: Octogenarians undergoing PCI had a higher rate of MACCE and mortality compared with a younger population. In octogenarians, MACCE in those with STEMI was significantly higher than those with NSTEMI/UA and the mortality trend was similar; however, the 1-year trend was in favor of the STEMI subgroup.

RESUMO

BACKGROUND: Unhealthy lifestyle behaviors are a major concern in the development of metabolic syndrome (MetS). This study aimed to develop, implement, and evaluate a lifestyle education package as a strategy to control the biomedical components of MetS. METHODS: A total of 72 women and men (aged 18-68 y) with MetS were selected through randomized sampling. They were classified into 2 groups: an intervention group that received a lifestyle educational package with close follow-ups and a control group that received only usual care. Anthropometric indices, blood pressure, lipid profiles, and fasting blood sugar were assessed at baseline and after 3 months. RESULTS: The lifestyle-modification program was associated with a modest weight loss (2 ± 0.4 kg; P < 0.001), a significant reduction in waist circumference (2.3 ± 0.9 cm; P < 0.001) and the hip circumference (1 ± 0.3 cm; P < 0.001), and a sharp decrease in diastolic blood pressure (5.3 ± 1.4 mm Hg; P < 0.001), compared with the baseline values in the intervention group. Additionally, according to the one-way MANOVA analysis, 33.8% of the changes in MetS components were attributable to the educational intervention (P < 0.001, F = 5.27). CONCLUSIONS: Improvement in lipid profile and anthropometric measures suggest that a lifestyle package based on multivariable health education is an acceptable method.

RESUMO

BACKGROUND: Serial chest computed tomography (CT) scans are used to detect coronavirus disease 2019 (COVID-19) pneumonia and monitor the disease course. This study investigates relationship between total severity score by first chest CT and the outcome of coronavirus COVID-19 patients with coronary artery disease (CAD). RESULTS: A total of 48 patients with a history of CAD (mean age=60.83±3.06 years, 75% male) with positive real-time reverse transcription-polymerase chain reaction for COVID-19 were included. Outcome was defined as acute respiratory distress syndrome or death. The unadjusted and adjusted effects of the CT score on the outcome were reported through odds ratio (OR) with 95% confidence interval (CI). Outcome occurred in 17 (35.5%) patients (8 deaths). The CT score was directly and significantly correlated with the outcome in the univariate analysis (OR 1.38, 95% CI 1.12-1.70; P=0.003) and remained significant after adjustment for diabetes, hypertension, body mass index, and serum level of highly sensitive C-reactive protein (OR 1.51, 95% CI 1.11-2.05; P=0.009). Outcome rate was 24.1% in patients with a CT score <2.5, whereas it was 8.3% in patients with a CT score>2.5. CONCLUSIONS: The first chest CT score could be a robust predictor of adverse events in confirmed COVID-19 patients with coronary artery disease.

RESUMO

OBJECTIVE: Acute ischemic cardiac events can complicate coronavirus disease 2019 (COVID-19). We report the in-hospital characteristics of patients with acute myocardial infarction and concomitant COVID-19. METHODS: This was a registry-based retrospective analysis of patients admitted with positive COVID-19 tests who suffered acute myocardial infarction either before or during hospitalization; from 1 March 2020 to 1 April 2020 in a tertiary cardiovascular center-Tehran Heart Center. We performed an exploratory analysis to compare the clinical characteristics of patients who died during hospitalization or were discharged alive. RESULTS: In March 2020, 57 patients who had acute myocardial infarction and a confirmed diagnosis of COVID-19 were included in the study. During hospitalization, 13 patients (22.8%) died after a mean hospital stay of 8.4 days. The deceased were older than the survivors. No significant association between mortality and sex or length of hospital stay was observed. Hypertensive individuals were more likely to have a fatal outcome. Previously receiving angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers did not show any association with mortality. Regarding the laboratory data during hospitalization, higher cardiac troponin T, neutrophil count, C-reactive protein, urea, and blood urea nitrogen/creatinine ratio were observed in the mortality group. The deceased had a lower lymphocyte count than the survivors. CONCLUSIONS: Markers of worsening renal function and immune system disturbance seem to be associated with mortality in concurrent acute myocardial infarction and COVID-19. Optimizing the management of acute coronary syndrome complicating COVID-19 requires addressing such potential contributors to mortality.

RESUMO

BACKGROUND: Primary percutaneous coronary intervention (PPCI) as the treatment of choice for ST­segment elevation myocardial infarction (STEMI) should be rapidly performed. It is necessary to use preventive strategies during the coronavirus disease 2019 (COVID­19) outbreak, which is an ongoing global concern. However, critical times in STEMI management may be influenced by the implementation of infection control protocols. AIMS: We aimed to investigate the impact of our dedicated COVID­19 PPCI protocol on time components related to STEMI care and catheterization laboratory personnel safety. A subendpoint analysis to compare patient outcomes at a median time of 70 days during the pandemic with those of patients treated in the preceding year was another objective of our study. METHODS: Patients with STEMI who underwent PPCI were included in this study. Chest computed tomography (CT) and real­time reverse transcriptase-polymerase chain reaction (rRT­PCR) tests were performed in patients suspected of having COVID­19. A total of 178 patients admitted between February 29 and April 30, 2020 were compared with 146 patients admitted between March 1 and April 30, 2019. RESULTS: Severe acute respiratory syndrome coronavirus 2 infection was confirmed by rRT­PCR in 7 cases. In 6 out of 7 patients, CT was indicative of COVID­19. There were no differences between the study groups regarding critical time intervals for reperfusion in STEMI. The 70­day mortality rate before and during the pandemic was 2.73% and 4.49%, respectively (P = 0.4). CONCLUSIONS: The implementation of the dedicated COVID­19 PPCI protocol in patients with STEMI allowed us to achieve similar target times for reperfusion, short­term clinical outcomes, and staff safety as in the prepandemic era.

RESUMO

Background: Reducing blood pressure through diet decreases the possibility of heart attacks, and lowering blood cholesterol can reduce the risk of coronary artery disease. The aim of the present study was to examine the effects of education based on the Health Belief Model on the dietary behavior of patients following coronary artery bypass graft surgery (CABG) at the Heart Surgery Department of Shahid Beheshti Hospital of Qom. Methods: In this semi-experimental clinical trial, data were collected on 64 patients, at an average age of 59.9 ± 7.26 years in the intervention group and 58.5 ± 7.6 years in the control group. Seventy percent of the study subjects were male and 30% were female. Intervention and control groups were given a questionnaire, comprising 56 questions in 5 parts. The educational intervention was aimed at creating perceived susceptibility and perceived severity in the intervention group. After 1 month. Both groups were tested, and the resulting data were analyzed to investigate the effects of the educational intervention on the nutritional knowledge and behavior of the patients. Results: According to the results, educational intervention caused a significant increase in the mean scores of knowledge (p value = 0.001), perceived severity (p value = 0.007), and perceived benefits and barriers (p value = 0.003) in the intervention group but did not cause a significant increase in the mean score of nutritional behavior (p value = 0.390). Conclusion: Education based on the Health Belief Model seems to be effective in improving nutritional knowledge, but more consistent and comprehensive educational programs are necessary in order to change behavior and improve nutritional behavior.
