RESUMO

BACKGROUND: From a large observational acute coronary syndrome registry in Côte d'Ivoire, we aimed to assess incidence, clinical presentation, management, and in-hospital outcomes for type 2 myocardial infarction (T2MI) compared with type 1 MI. METHODS AND RESULTS: We conducted a cross-sectional monocentric study using data from REACTIV (Registre des Infarctus de Côte d'Ivoire) at the Abidjan Heart Institute. All patients hospitalized with MI between 2018 and 2022 who underwent coronary angiography were included. For each patient, sociodemographic data, cardiovascular risk factors and history, and clinical and paraclinical presentation were collected at admission. In-hospital outcomes, including major adverse cardiovascular events and mortality, were reported. Among 541 consecutive patients hospitalized with MI, 441 met the definition of type 1 MI or T2MI. T2MI accounted for 14.1% of cases. Patients with T2MI showed a trend toward slightly younger age (54 versus 58 years, P=0.09). Patients with T2MI seemed to have less severe coronary artery disease, with less frequent multivessel disease (P<0.001). Main triggering factors for T2MI were coronary embolism (24.2%), severe hypertension with or without left ventricular hypertrophy (22.6%), and tachyarrhythmia (16.1%). In-hospital event rates were low in both MI types. Although the difference was nonsignificant, death rates for patients with type 1 MI tended to be higher than for patients with T2MI, as well as occurrence of major adverse cardiovascular events. CONCLUSIONS: Our study revealed disparities in clinical characteristics, angiographic features, cause, and in-hospital outcomes in T2MI in our population compared with Western populations. These results suggest the heterogeneity of T2MI and the potential causative and demographic variability depending on geographical area.

RESUMO

Underlying coronary artery disease (CAD) is increasingly considered to be a key issue in the pathophysiology of type 2 myocardial infarction (T2MI). In T2MI, which is attributable to a mismatch between oxygen supply/demand, CAD is common and appears to be more severe than in type 1 myocardial infarction (T1MI). Little is known about the heterogeneous mechanisms that cause supply/demand imbalance and non-coronary triggers leading to myocardial ischemia or about how they are potentially modulated by the presence and severity of CAD. CAD seems to be underrecognized and undertreated in T2MI, even though previous studies have demonstrated both the short and long-term prognostic value of CAD in T2MI. In this literature review, we attempt to address the prevalence and severity of CAD, challenges in the discrimination between T2MI and T1MI in the presence of CAD, and the prognostic value of CAD among patients with T2MI.

RESUMO

BACKGROUND: A new classification of type 1 and 2 myocardial infarction (MI) derived from the fourth universal definition of MI (UDMI) has been recently proposed, based on pathophysiology of coronary artery disease (CAD). We assessed the impact of this new MI categorization on epidemiology and outcomes, considering type 1 MI (T1MI) and type 2 MI (T2MI), with and without CAD. METHODS: Retrospective study including all consecutive patients hospitalized for an acute MI in a multicenter database (RICO). MI was defined according to current UDMI. Rates and outcomes of T1MI and T2MI were addressed according to the new classification. RESULTS: Among the 4,573 patients included in our study, 3,710 patients (81.1%) were initially diagnosed with T1M1 and 863 (18.9%) with T2MI. After reclassification, 96 T2MI patients were moved into the T1MI category. Out of the remaining 767 patients with T2MI, 567 underwent coronary angiography, and were adjudicated as type 2A MI (68.6%) with obstructive CAD, and type 2B MI (31.4%) without obstructive CAD. When compared with T1MI and T2BMI, T2AMI patients had worse in-hospital outcomes, including severe heart failure (P < .001), atrial fibrillation or flutter (P < .001) and severe bleeding (P < .001). Kaplan-Meier 1-year survival curves showed higher all-cause and CV causes mortality in T2AMI patients compared to T1MI and T2BMI (P < .001). In multivariate Cox regression analysis, type of MI was independent predictor of death. CONCLUSION: Our large observational multicenter study shows major disparities in mortality according to type of MI and support the relevance of the new MI classification to improve risk classification, taking into account CAD in T2MI. Our findings may help identifying specific phenotypes and considering personalized diagnostic and management strategies.

RESUMO

Introduction: Heart rate recovery (HRR) measured during stress tests, assesses the vago-sympathetic balance. It is a known prognostic and predictive parameter of cardiovascular mortality that is believed to be correlated with the presence and severity of coronary artery disease. The aim of this work was to assess the predictive value of heart rate recovery in the diagnostic and severity of coronary lesions in a major metropolis of sub-Saharan Africa where access to specialist care is unevenly distributed. Patients and method: We conducted a retrospective observational study from January 2010 to February 2020 at the Abidjan Cardiology Institute, including patients who performed a diagnostic coronary angiography after a positive exercise test. Clinical, angiographic and exercise parameters were analyzed and compared in patients with abnormal heart rate recovery (HRR) and those with normal one. Results: The main study limitation is small sampling due to the cost of the angiographic procedure which limits its realization. We recorded 41 subjects whose mean age was 53.4 ± 9.6 years with a male predominance (sex ratio of 3.6). The predominant age group was between 50 and 60 years. Males were older than females with no significant difference. The predominant cardiovascular risk factors were overweight/obesity (68.29%) and hypertension (61%). Eight patients (19.5%) presenting an abnormal HRR (≤12 bpm) had more significant coronary disease (p=0.02) and more severe ones (p=0.003). Patients with abnormal HRR tended to be older without statistical significance (p=0.081), and had lower chronotropic reserve and maximum heart rate (p=0.008 and p=0.042, respectively). The positive predictive value of HHR was 87.5% and its negative predictive value was 60.6%. Conclusion: Abnormal HRR can predict the presence of coronary artery disease and its severity. Evaluating HRR during stress tests could help in the detection, evaluation, and monitoring of ischemic heart disease in our resource-limited countries.

RESUMO

Introduction-Objective: Acute coronary syndromes (ACS) are the leading cause of death among the elderly in sub-Saharan Africa. The aim of this study was to analyze the characteristics of ACS among the elderly at the Abidjan Heart Institute. Materials and methods: Cross-sectional study from January 1, 2015, to December 31, 2019. All patients aged 18 or more admitted to the Abidjan Heart Institute for ACS were included. These patients were divided into two groups: elderly (≥ 65 years old) and non-elderly (< 65 years old). Clinical data, management and outcomes were compared and analyzed in both groups. Results: A total of 570 patients were included, of which 137 (24%) were elderly. Sixty percent (60%) of elderly patients presented with ST Segment Elevation Myocardial Infarction (STEMI). Percutaneous coronary intervention (PCI) was less performed among elderly patients (21.1% vs 30.2%, p = 0.039). Heart failure was the most important complication among the elderly group (56.9% vs 44.6%, p = 0.012). In-hospital mortality was 8% among the elderly. Predictive factors for in-hospital mortality were history of hypertension (HR 2.58; CI95% 1.10-6.08) and STEMI presentation (OR 11.60; CI95% 2.70-49.76). PCI was a protective factor for in-hospital mortality (OR 0.14; IC95% 0.03-0.62). Conclusion: ACS occur with increasing frequency with age. Poor outcomes among the elderly are determined by the clinical presentation and comorbidities. PCI appears to significantly reduce in-hospital mortality.

RESUMO

Background Data in the literature on acute coronary syndrome in sub-Saharan Africa are scarce. Methods and Results We conducted a systematic review of the MEDLINE (PubMed) database of observational studies of acute coronary syndrome in sub-Saharan Africa from January 1, 2010 to June 30, 2020. Acute coronary syndrome was defined according to current definitions. Abstracts and then the full texts of the selected articles were independently screened by 2 blinded investigators. This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. We identified 784 articles with our research strategy, and 27 were taken into account for the final analysis. Ten studies report a prevalence of acute coronary syndrome among patients admitted for cardiovascular disease ranging from 0.21% to 22.3%. Patients were younger, with a minimum age of 52 years in South Africa and Djibouti. There was a significant male predominance. Hypertension was the main risk factor (50%-55% of cases). Time to admission tended to be long, with the longest times in Tanzania (6.6 days) and Burkina Faso (4.3 days). Very few patients were admitted by medicalized transport, particularly in Côte d'Ivoire (only 34% including 8% by emergency medical service). The clinical presentation is dominated by ST-elevation sudden cardiac arrest. Percutaneous coronary intervention is not widely available but was performed in South Africa, Kenya, Côte d'Ivoire, Sudan, and Mauritania. Fibrinolysis was the most accessible means of revascularization, with streptokinase as the molecule of choice. Hospital mortality was highly variable between 1.2% and 24.5% depending on the study populations and the revascularization procedures performed. Mortality at follow-up varied from 7.8% to 43.3%. Some studies identified factors predictive of mortality. Conclusions The significant disparities in our results underscore the need for a multicenter registry for acute coronary syndrome in sub-Saharan Africa in order to develop consensus-based strategies, propose and evaluate tailored interventions, and identify prognostic factors.

RESUMO

BACKGROUND: Although patients with familial heterozygous hypercholesterolemia (FH) have a high risk of early myocardial infarction (MI), the coronary artery disease (CAD) burden in FH patients with acute MI remains to be investigated. METHODS: The data for all consecutive patients hospitalized in 2012-2019 for an acute MI and who underwent coronary angiography were collected from a multicenter database (RICO database). FH (n = 120) was diagnosed using Dutch Lipid Clinic Network criteria (score ≥ 6). We compared the angiographic features of MI patients with and without FH (score 0-2) (n = 234) after matching for age, sex, and diabetes (1:2). RESULTS: Although LDL-cholesterol was high (208 [174-239] mg/dl), less than half of FH patients had chronic statin treatment. When compared with non-FH patients, FH increased the extent of CAD (as assessed by SYNTAX score; P = 0.005), and was associated with more frequent multivessel disease (P = 0.004), multiple complex lesions (P = 0.022) and significant stenosis location on left circumflex and right coronary arteries. Moreover, FH patients had more multiple lesions, with an increased rate of bifurcation lesions or calcifications (P = 0.021 and P = 0.036, respectively). In multivariate analysis, LDL-cholesterol levels (OR 1.948; 95% CI 1.090-3.480, P = 0.024) remained an independent estimator of anatomical complexity of coronary lesions, in addition to age (OR 1.035; 95% CI 1.014-1.057, P = 0.001). CONCLUSIONS: FH patients with acute MI had more severe CAD, characterized by complex anatomical features that are mainly dependent on the LDL-cholesterol burden. Our findings reinforce the need for more aggressive preventive strategies in these high-risk patients, and for intensive lipid-lowering therapy as secondary prevention.

RESUMO

Optimal antithrombotic therapy after percutaneous coronary intervention (PCI) in patients on oral anticoagulants (OAC) remains a clinical conundrum. In fact, combining an OAC with dual antiplatelet therapy (triple antithrombotic therapy, TAT) increases the risk of bleeding. Clopidogrel is the only thienopyridine recommended in TAT patients. Whether its response plays a relevant role in this setting remains uncertain. We aimed to evaluate the level of platelet reactivity inhibition (PRI) achieved by oral TAT in Acute Coronary Syndrome (ACS) patients undergoing PCI and its relationship with outcomes. We performed a multicenter prospective observational study and assessed PRI by vasodilator-stimulated phosphoprotein (VASP) index following a loading dose of clopidogrel. The primary endpoint was the incidence of major adverse cerebral or cardiovascular events (MACCE) at six months based on High on Treatment Platelet Reactivity (HTPR, VASP > 50%). The secondary endpoint was the incidence of bleeding at six months based on Low on Treatment Platelet Reactivity (LTPR, VASP < 16%). 491 patients were followed up for six months: 7.7% experienced MACCE and 17.3% experienced bleeding. There was no significant relationship between HTPR and MACCE, neither between LTPR and bleeding. Vitamin-K antagonist (VKA) treatment was associated with more MACCE and bleeding events, and the majority of events occurred within the first months. VASP index failed to predict outcomes in post-ACS patients with TAT. We confirm that direct acting OAC should be prioritized over VKA in TAT regimen.

RESUMO

This review was conducted to emphasize the complex interplay between atrial fibrillation (AF) and myocardial infraction (MI). In type 1 (T1) MI, AF is frequent and associated with excess mortality. Moreover, AF after hospital discharge for T1MI is not rare, suggesting the need to improve AF screening and to develop therapeutic strategies for AF recurrence. Additionally, AF is a common trigger for type 2 MI (T2MI), and recent data have shown that tachyarrhythmia or bradyarrhythmia could be a causal factor in, respectively, 13-47% or 2-7% of T2MI. In addition, AF is involved in T2MI pathogenesis as a result of severe anemia related to anticoagulants. AF is also an underestimated and frequent cause of coronary artery embolism (CE), as a situation at risk of myocardial infarction with non-obstructive coronary arteries. AF-causing CE is difficult to diagnose and requires specific management. Moreover, patients with both AF and chronic coronary syndromes represent a therapeutic challenge because the treatment of AF include anticoagulation, depending on the embolic risk, and ischemic heart disease management paradoxically includes antiplatelet therapy.

RESUMO

INTRODUCTION: Renal transplant recipients have a high peri-operative risk for cardiovascular events. The post-transplantation period also carries a risk of myocardial infarction (MI). Coronary artery disease (CAD) is a leading cause of death in these patients. We aimed to assess the risk of MI, the specific morbidity profile of MI after transplantation as well as the long-term prognosis after MI in renal transplantation (RT) patients regarding cardiovascular (CV) death and all-cause death. METHODS: From a French national medical information database, all of the patients seen in French hospitals in 2013 with at least 5-years follow-up were retrospectively identified and patients without transplantation but with previous dialysis at baseline were excluded. There were 17,526 patients with RT and 3,288,857 with no RT. RESULTS: Among these patients, 1020 in the RT group (5.8%), and 93,320 in the non-RT group (2.8%) suffered acute MI during a median follow-up of 5.4 years. After multivariable adjustment, risk of MI was higher in RT patients than in non-RT patients (HR 1.45, IC 95% 1.35-1.55). The mean age was 59.5 years for transplant patients with MI, and 70.6 years for the reference population with MI (p < 0.0001). MI patients with RT (vs. non RT patients) were more likely to have hypertension, diabetes dyslipidemia, and peripheral artery disease (76.0% vs. 48.1%, 38.7% vs. 25.2%, 33.2% vs. 23.2%, and 31.2% vs. 17.3%, respectively, p < 0.0001). Incidence of non ST-elevation MI (NSTEMI) was higher in RT patients while incidence of ST-elevation MI (STEMI) was higher in patients without RT. In unadjusted analysis, risk of all-cause death and CV death within the first month after MI were higher in patients without RT (18% vs. 11.1% p < 0.0001 and 12.3% vs. 7.8%, p < 0.0001, respectively). However, multivariable analysis indicated that risk of all-cause death was higher in patients with RT than in those with no RT (adjusted HR 1.15 IC 95% 1.03-1.28). CONCLUSIONS: MI is not an uncommon complication after RT (incidence of around 5.8% after 5 years). RT is independently associated with a 45% higher risk of MI than in patients without RT, with a predominance of NSTEMI. MI in patients with RT is independently associated with a 15% higher risk of all-cause death than that in patients with MI and no RT.

RESUMO

AIM: The aim of the study was to determine the relationship between acute hyperglycaemia and in-hospital mortality in black Africans with acute coronary syndromes (ACS). METHODS: From January 2002 to December 2017, 1 168 patients aged ≥ 18 years old, including 332 patients with diabetes (28.4%), consecutively presented to the intensive care unit of the Abidjan Heart Institute for ACS. Baseline data and outcomes were compared in patients with and without hyperglycaemia at admission (> 140 mg/dl; 7.8 mmol/l). Predictors for death were determined by multivariate logistic regression. RESULTS: The prevalence of admission hyperglycaemia was 40.6%. It was higher in patients with diabetes (55.3%). In multivariate logistic regression, acute hyperglycaemia (hazard ratio = 2.33; 1.44-3.77; p < 0.001), heart failure (HR = 2.22; 1.38-3.56; p = 0.001), reduced left ventricular ejection fraction (HR = 6.41; 3.72-11.03; p < 0.001, sustained ventricular tachycardia or ventricular fibrillation (HR = 3.43; 1.37-8.62; p = 0.008) and cardiogenic shock (HR = 8.82; 4.38-17.76; p < 0.001) were predictive factors associated with in-hospital death. In sub-group analysis according to the history of diabetes, hyperglycaemia at admission was a predictor for death only in patients without diabetes (HR = 3.12; 1.72-5.68; p < 0.001). CONCLUSIONS: In ACS patients and particularly those without a history of diabetes, admission acute hyperglycaemia was a potentially threatening condition. Appropriate management, follow up and screening for glucose metabolism disorders should be implemented in these patients.

RESUMO

BACKGROUND: Implementation of primary percutaneous coronary intervention (PCI) in sub-Saharan Africa remains a challenging issue. The aim of this study was to report the results of primary PCI and outcomes in the catheterisation laboratory of the Abidjan Heart Institute. METHODS: Between April 2010 and March 2019, all patients aged 18 years presenting to the Abidjan Heart Institute for ST-segment elevation myocardial infarction (STEMI) over the study period and who underwent primary PCI were included. We considered primary PCI when it was performed within 48 hours of the onset of symptoms. Baseline data, PCI characteristics and outcomes were analysed. RESULTS: Among a total of 780 patients hospitalised for STEMI, 471 were admitted within 48 hours of the onset of symptoms. One-hundred and sixty six patients underwent primary PCI, with a ratio of primary PCI/STEMI of up to 21.3%. One hundred and six patients (63.9%) were admitted within 12 hours of the onset of symptoms. The femoral approach was the most commonly used (78.3%). Primary PCI was performed with stent implantation in 84.3% of patients. Drug-eluting stents (DES) were used in 42.1% of patients. In most cases, angiographic success was observed (157/166, 94.6%). Non-fatal complications were mainly haematomas (3.6%). Peri-procedural mortality rate was 1.2%. CONCLUSIONS: Primary PCI can be performed safely in some small-volume centres in sub-Saharan Africa. Healthcare policies and regional networks must be encouraged in order to improve management of STEMI patients.

RESUMO

BACKGROUND: Individuals with heterozygous familial hypercholesterolemia (FH) are at high risk of early myocardial infarction (MI). However, coronary artery disease (CAD) burden of FH remains not well described, especially for French patients. OBJECTIVE: The objective of this study was to assess the prevalence of FH and severity of CAD from a large database of a French regional registry of acute MI. METHODS: All consecutive patients hospitalized for an acute MI in a multicenter database from 2001 to 2017 were considered. FH was diagnosed using an algorithm adapted from the Dutch Lipid Clinic Network criteria. The prevalence and clinical features of FH and the severity of CAD were assessed. RESULTS: Among the 11,624 patients included in the study, the proportion of "probable/definite", "possible", and "unlikely" FH in patients with MI was 2.1% (n = 249), 20.7% (n = 2405), and 77.2% (n = 8970), respectively. When compared with patients with "unlikely" FH, patients with "probable/definite" FH were 20 years younger (51 vs 71, P < .001), with a lower rate of diabetes (17% vs 25%, P = .007) and a higher prevalence of personal and familial history of CAD. Chronic statin treatment was only used in 48% of FH patients and ezetimibe in 8%. After adjustment for age, sex, and diabetes, patients with FH were characterized by increased extent of CAD (SYNTAX score 11 vs 7, P < .001) and multivessel disease (55% vs 40%, P < .001). CONCLUSIONS: In this large cohort of French individuals, FH was common in patients with MI, associated with markedly early age of MI and severity of CAD burden and limited use of preventive lipid-lowering therapy.

RESUMO

INTRODUCTION: acute coronary syndromes (ACSs) have been increasing in sub-Saharan Africa. Coronary angiography data have been rarely reported. This study aims to investigate coronary lesions observed in patients with acute coronary syndromes (ACS) in Abidjan. METHODS: we conducted a cross-sectional study from 1st January 2010 to 31st December 2014. All patients with ACS admitted to the Abidjan Heart Institute and undergoing coronary angiography during the study period were included. Two hundred and fifty-six patients were selected. We investigated and compared coronary lesions in patients with ACS associated with persistent ST-segment elevation (ACS ST+) and in those with ACS without ST-segment elevation (ACS ST-). RESULTS: the average age of patients was 53.2 ± 10.8 years; there was a male predominance, with a sex ratio of 6.1. Abnormal coronary angiography rate was significantly higher in the STEMI group (95.4% and 64.2% respectively, p < 0.001). Three hundred and four coronary lesions were found in the STEMI group against 43 in the NSTE-ACS group. Stenotic lesions were predominantly one-vessel disease (45.3%) in the STEMI group and two or three-vessel disease in the NSTE-ACS group (68.0%). Type B1 lesions were more common in the NSTE-ACS group (62.8% versus 36.5%, p = 0.002). The most complex type C lesions were more commonly found in the STEMI group (17.8%), with no significant difference. The majority of patients had SYNTAX score less than 22, whatever the type of ACS (87.4% in the STEMI group and 90.1% in the NSTE-ACS group). CONCLUSION: coronary lesions in the patients group with STEMI were predominantly one-vessel disease and they were more diffuse in the NSTE-ACS group, but with a higher proportion of angiographically normal coronary arteries. The management of patients with these lesions is based in the majority of cases on coronary angioplasty.

RESUMO

AIM: To describe the coronary angiographic aspects observed in patients with dilated cardiomyopathies (DCM) in a sub-Saharan African country in order to improve their management. METHODS: This was a cross-sectional study conducted from 1 January 2010 to 31 March 2016. All patients aged 18 years and older, presenting with DCM and admitted to Abidjan Heart Institute, who underwent coronary angiography were included. One hundred and eight patients were selected. We analysed and compared the coronary angiographic features observed. RESULTS: The median age of our patients was 52 years (46-61). There was a male predominance (sex ratio = 3). Hypertension (53.7%) was the major cardiovascular risk factor found. Coronary angiography was abnormal in 37 patients (34.3%). Twenty-three patients (21.3%) had obstructive coronary artery disease (CAD). Patients with CAD were older than those with normal coronary arteries, but with no statistically significant difference (p = 0.06). Hypertension (p < 0.001) and diabetes (p = 0.0003) were statistically significantly more commonly reported in patients with CAD. CONCLUSIONS: Ischaemic heart disease is likely to be underdiagnosed in sub-Saharan Africa. A coronary angiographic assessment of patients receiving treatment for DCM, especially in the presence of cardiovascular risk factors, should help optimise their management and improve prognosis.

RESUMO

BACKGROUND: Coronary angiography data are scarce for black patients with diabetes. AIM: To assess coronary angiography findings in patients with diabetes at the Abidjan Heart Institute. METHODS: This observational cross-sectional survey was conducted between 1 April 2010 and 31 December 2014. All patients admitted for known or suspected coronary artery disease who underwent coronary angiography were included in the Registre Prospectif des Actes de Cardiologie Interventionnelle de l'Institut de Cardiologie d'Abidjan. We analysed and compared coronary angiographical findings in patients with and without diabetes. RESULTS: Eighty patients with diabetes were compared with 353 patients without diabetes. Patients with diabetes were significantly older (58.7±8.9 vs 52.1±11.5 years; P<0.001). Hypertension and hypertriglyceridaemia were significantly associated with diabetes (P<0.001 and P=0.04, respectively). A higher proportion of patients with diabetes had an abnormal coronary angiogram (85.0% vs 67.7%; P=0.002). Coronary artery disease in patients with diabetes was predominantly characterized by multivessel disease (P<0.001). Cardiovascular risk factors associated with diabetes influenced the severity of coronary lesions. A SYNTAX score≥33 was found in a higher proportion of patients with diabetes (12.5% vs 7.1%). In the multivariable logistic regression, after adjustment, age>60 years (hazard ratio 2.53, 95% confidence interval 1.59-4.04; P<0.001) and diabetes (hazard ratio 2.12, 95% confidence interval 1.26-3.57; P=0.004) were associated with multivessel coronary artery disease. CONCLUSIONS: In our study, diabetes emerged as a risk factor for multivessel coronary artery disease. Future studies should help to define the long-term prognosis of these patients, and to assess the benefits of myocardial revascularization procedures.

RESUMO

BACKGROUND: Major in-hospital mortality rate in patients with ST-segment Elevation Myocardial Infarction (STEMI) in Sub-Saharan Africa has been reported. Data on follow-up in these patients with STEMI are scarce. We aimed to assess medium and long-term prognosis in patients with STEMI admitted to Abidjan Heart Institute. METHODS: Prospective cohort study including 260 patients admitted for STEMI to Abidjan Heart Institute, from January 1, 2012 to December 31, 2015. We compared mortality and nonfatal cardiovascular complications in revascularized and non-revascularized groups. Survival curve was generated with the Kaplan-Meier method. Predictors of mortality after STEMI were determined by multivariable Cox regression. RESULTS: Of the 260 patients followed up on a median period of 39 months [28-68 months], 94 patients (36.1%) were revascularized and 166 (63.8%) were non-revascularized. Crude all-cause mortality was 10.4%. It was significantly higher in non-revascularized patients (p = 0.04). There was no difference in the occurrence of nonfatal cardiovascular complications in the 2 groups. In multivariable Cox regression, age ≥ 70 years, female gender and heart failure were the predictive factors for death after adjustment. CONCLUSIONS: STEMI remains an important cause of mortality in our practice. Healthcare policies should be developed to improve patient care and long-term outcomes.
