Inverted Takotsubo Following a Ruptured Ectopic Pregnancy, Treated with Levosimendan.

Background: Takotsubo syndrome is a transient stunned myocardium that typically involves the apical and mid-ventricular segments. A variant, called Inverted Takotsubo, concerns the basal and mid-ventricular segments. Case summary: We present a ruptured ectopic pregnancy that was responsible for a catecholamine surge, which led to this stress-induced cardiomyopathy. Transthoracic echocardiography showed mid-basal segments akinesia and hypercontractility of the apical segments. Biology has shown mild elevated troponin and NT-pro-BNP levels which led to performing a coronary angiography that showed no angiographic stenosis. A left ventricle angiography evoked the diagnosis of inverted Takotsubo. The patient has received Levosimendan to allow progressive weaning of catecholamine inotropes. The clinical evolution was favorable. Echocardiography performed after 3 weeks, showed ad-integrum restitution of the left ventricular function. Discussion: Takotsubo syndrome should be evoked whenever a context of physical or psychological stress is present. We underline the usefulness of Levosimendan as a nonadrenergic inotrope in this particular context.

[Incidence of adverse events associated with the peripheral venous catheter in a Tunisian university hospital]. / Incidence des événements indésirables associés au cathéter veineux périphérique dans un service de cardiologie, Tunisie.

OBJECTIVE: To determine the incidence of peripheral venous catheters-related adverse events (PVCAEs). METHODS: We conducted a prospective observational study in the cardiology department over a period of 3 months. All inserted PVCs were monitored (every 12 hours) from insertion to up to 48 hours after removal. RESULTS: Data were analyzed for 148 patients with a mean age of 63.37±12.26 years and male predominance (n=76, 51.4%). The most common medical history was high blood pressure (56.1%) followed by obesity (39.2%). Intake of antibiotics was noted in 16.2% of cases where amoxicillin-clavulanic acid was the most prescribed molecule (4.1%). A total of 210 PVCs was studied (794 PVC-days). The mean maintenance time was 5.36±3.95 days. 38 PVCs resulted in 70 AEs with an incidence of 33.33 % (8.81 per 1000 PVC-days). The most common complication was pain (n=35, 50%), followed by mechanical PVCAEs (n=22, 31.42%). CONCLUSION: The incidence of PVCAEs remains high. The analysis of the main risk factors for these AEs would make better the identification of the preventive actions that should be undertaken.

A retrospective study from a single center to compare outcomes in 79 patients with in-stent restenosis treated with paclitaxel-coated balloon angioplasty or drug-eluting stent implantation.

BACKGROUND: Despite the recent progress made in drug-eluting stents (DESs), in-stent restenosis (ISR) is still a common complication of percutaneous coronary interventions. This retrospective study from a single center aimed to compare outcomes in 79 patients with ISR treated with paclitaxel-coated balloon (PCB) angioplasty or DES implantation. RESULTS: From January 2017 to December 2021, 83 ISR lesions from 79 patients were included. Thirty-two were treated with PCB and 51 treated with available DES in the catheterization laboratory. Baseline characteristics were similar in both groups. Mean time between index angioplasty and restenosis was 27 months with a minimum of 4 months and a maximum of 70 months. Concerning Mehran ISR angiographic classification, classes II and III were more likely treated with DES. Stenosis diameter and minimal lumen diameter (MLD) were similar in both groups. PCB used was significantly shorter than DES: Mean length was 19.75 ± 5.7 versus 22.1 ± 16.5 (p < 0.001), respectively. Angiographic results immediately after intervention were similar in both groups: In-segment MLD after the procedure was 2.5 ± 0.4 in the DES group and 2.26 ± 0.55 in the PCB group. A median follow-up of 20 months was achieved for 68 patients, and 11 were lost to follow-up. There was also no difference in both groups regarding free from events survival. CONCLUSIONS: The findings from this study support recent international studies that have shown no significant differences between DES and PCB and in-stent restenosis. This suggests that PCB use is an option to consider in our local daily practice.

Combination Therapy With Nicardipine and Isosorbide Dinitrate to Prevent Spasm in Transradial Percutaneous Coronary Intervention (from the NISTRA Multicenter Double-Blind Randomized Controlled Trial).

Verapamil and nitroglycerin are widely used to prevent radial artery spasm (RAS) during percutaneous cardiovascular procedures. However, these agents are not typically available in most African countries and consequently, isosorbide dinitrate is often the only spasmolytic treatment. Our aim was to compare the efficacy of isosorbide dinitrate alone versus isosorbide dinitrate used together with nicardipine to prevent RAS during transradial coronary procedures. This was a randomized controlled double-blind multicenter trial. Patients (n = 1,523) were randomized to receive either a sole therapy of isosorbide dinitrate (n = 760) or the combination of isosorbide dinitrate and nicardipine (n = 763). Our primary end point was the occurrence of RAS; defined as considerable perceived hindrance of catheter advancement. Our secondary end points were severe RAS; defined as (1) severe arm pain, (2) the need for either morphine or midazolam treatment, and (3) necessity for crossover to the contralateral radial or femoral artery. RAS incidence was reduced with the combination therapy versus isosorbide dinitrate alone (15% vs 25%, p <0.001), with a number needed to treat of 10 patients. There was also a significant reduction in the incidence of the secondary end points with combination therapy (3.6% vs 8.2%, p <0.001), with a number needed to treat of 22 patients. This result was driven by reductions in both femoral crossover (0.5% vs 2.4%, p = 0.003) and the use of morphine or midazolam injections (1.6% vs 3.5%, p = 0.02) with combination therapy. In conclusion, we demonstrated the superiority of the combination therapy of isosorbide dinitrate and nicardipine over isosorbide dinitrate alone in reducing the incidence of RAS.

[Clinical impact of SARS-CoV2 infection in professional footballers of the Tunisian Premier League]. / Impact clinique de l'infection par le SARS-CoV2 chez les footballeurs professionnels de la première ligue Tunisienne.

AIM OF THE STUDY: The aim of our work, developed within the Tunisian Football Federation (TFF), was to study the clinical manifestations and the possible cardiac complications in professional footballers of the first league having contracted an infection by SARS-CoV2. PATIENTS AND METHODS: This is a retrospective, descriptive, and analytical study. Professional Premier League football players who contracted COVID-19 from the onset of the pandemic through June 2021 were included. RESULTS: Among the 1388 players of the Tunisian first professional league, 102 players (7.35%) had COVID-19. Three were excluded for lack of clinical data. The average age of the subjects included was 26 ± 4 years with extremes ranging from 19 to 37 years. The most frequent clinical manifestations were anosmia, agueusia and muscle fatigue. The clinical examination was normal in all the subjects included except for the presence of fever among 37 (37.9%) subjects. All subjects' electrocardiogram did not show any unusual abnormality. As for the imaging data, two players presented a pericardial effusion without signs of severity. In the other players, echocardiography was normal. Cardiac magnetic resonance imaging did not reveal any abnormality. CONCLUSION: The results of our study showed that there was no severe form of COVID-19 among professional soccer players. Larger scale studies integrating other leagues and different sport categories may provide more information on the clinical impact of this disease in high level athletes.

Outcomes and prognostic factors of patients treated for in-stent restenosis: a retrospective single-center experience.

BACKGROUND: The incidence of in-stent restenosis (ISR) remains relatively common despite the use of drug-eluting stents. Outcomes and prognostic factors following ISR revascularization are still being investigated. We aimed to describe the outcomes following different ISR treatment strategies in order to identify prognostic factors associated with worse outcomes. RESULTS: In a retrospective cohort study, we included patients who were admitted to our department and treated for ISR, from January 2017 to December 2018. All patients were followed up for a median period of 24 months. Major cardiac adverse event (MACE) was a composite outcome of the following events: myocardial infarction, target vessel revascularization, target lesion revascularization or cardiovascular death. MACEs were collected during follow-up. Our population consisted of 116 patients. Mean age was 60 years old with a sex ratio of 2.8. During follow-up, 44 patients (37.9%) had at least one MACE. Independent factors identified by multivariate logistic regression were ISR of the proximal left anterior descending artery [Odds ratio (OR) = 1.29; 95% confidence interval (95% CI) 1.16-1.81; p = 0.05], diffuse ISR [OR = 2.16; 95% CI 1.1-3.47; p = 0.022], double or triple vessel disease [OR = 2.97; 95% CI 1.2-6.8; p = 0.008], two or more stents per lesion [OR = 1.82; 95% CI 1.14-2.21, p = 0.031] and absence of post-dilatation in the initial angioplasty [OR = 1.32; 95% CI 1-1.35; p = 0.04]. CONCLUSIONS: Our study suggested that ISR is related to poor outcomes. Identifying prognostic factors would play a key role in the refinement of interventional techniques.

Prognostic impact of diabetes mellitus on patients managed by urgent percutaneous coronary intervention.

INTRODUCTION: Diabetes Mellitus (DM) is known to be associated with worse outcomes following percutaneous coronary intervention (PCI). AIM: To assess prognostic impact of DM on patients managed by urgent PCI following ST-segment elevation myocardial infarction (STEMI). METHODS: In a retrospective study, STEMI patients admitted to our department from January 2016 to December 2019 and treated with urgent PCI (primary or rescue PCI) were included. They were divided in two groups: Diabetic and non-diabetic patients. They were followed-up for a period of 12 months. Major cardiac adverse event (MACE) was a composite outcome of the following events: myocardial infarction, target vessel revascularization, target lesion revascularization or cardiovascular death. MACEs were collected during follow-up. RESULTS: Our population consisted of 225 patients. DM was observed in 104 STEMI patients (46.2%). Diabetic patients had higher frequency of hypertension (p 1.4mmol/l (p 75 years, hyperglycemia at admission (>10mmol/l), extensive anterior infarction and procedure failure were associated with in-hospital mortality in the non-diabetic group. Factors associated with 12-months mortality and MACEs among diabetic patients were age > 75 years, anemia, CKD and left ventricular systolic dysfunction. CONCLUSIONS: Despite modern era of STEMI treatment, diabetic patients still have a poor prognosis. These results highlight the need for coronary risk factors treatment among these patients.

Design and Rationale of the National Tunisian Registry of Percutaneous Coronary Intervention: Protocol for a Prospective Multicenter Observational Study.

BACKGROUND: Coronary artery diseases remain the leading cause of death in the world. The management of this condition has improved remarkably in the recent years owing to the development of new technical tools and multicentric registries. OBJECTIVE: The aim of this study is to investigate the in-hospital and 1-year clinical outcomes of patients treated with percutaneous coronary intervention (PCI) in Tunisia. METHODS: We will conduct a prospective multicentric observational study with patients older than 18 years who underwent PCI between January 31, 2020 and June 30, 2020. The primary end point is the occurrence of a major adverse cardiovascular event, defined as cardiovascular death, myocardial infarction, cerebrovascular accident, or target vessel revascularization with either repeat PCI or coronary artery bypass grafting (CABG). The secondary end points are procedural success rate, stent thrombosis, and the rate of redo PCI/CABG for in-stent restenosis. RESULTS: In this study, the demographic profile and the general risk profile of Tunisian patients who underwent PCI and their end points will be analyzed. The complexity level of the procedures and the left main occlusion, bifurcation occlusion, and chronic total occlusion PCI will be analyzed, and immediate as well as long-term results will be determined. The National Tunisian Registry of PCI (NATURE-PCI) will be the first national multicentric registry of angioplasty in Africa. For this study, the institutional ethical committee approval was obtained (0223/2020). This trial consists of 97 cardiologists and 2498 patients who have undergone PCI with a 1-year follow-up period. Twenty-eight catheterization laboratories from both public (15 laboratories) and private (13 laboratories) sectors will enroll patients after receiving informed consent. Of the 2498 patients, 1897 (75.9%) are managed in the public sector and 601 (24.1%) are managed in the private sector. The COVID-19 pandemic started in Tunisia in March 2020; 719 patients (31.9%) were included before the COVID-19 pandemic and 1779 (60.1%) during the pandemic. The inclusion of patients has been finished, and we expect to publish the results by the end of 2022. CONCLUSIONS: This study would add data and provide a valuable opportunity for real-world clinical epidemiology and practice in the field of interventional cardiology in Tunisia with insights into the uptake of PCI in this limited-income region. TRIAL REGISTRATION: Clinicaltrials.gov NCT04219761; https://clinicaltrials.gov/ct2/show/NCT04219761. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR1-10.2196/24595.

[Permanent cardiac pacing: about 234 patients]. / La stimulation cardiaque permanente : à propos de 234 patients.

BACKGROUND: Permanent cardiac pacing remains the only effective treatment for chronic, symptomatic bradycardia. In recent years, the role of implantable pacing devices has expanded substantially. AIM: To compare the situation of patients with critical brady arrhythmias before and after pacing focusing on indication for pacemaker implantation, frequency of re intervention and early and late complications. METHODS: Retrospective study performed over 24 years between 1984 and 2007 at the department of cardiology of Farhat Hached hospital. A total of 234 patients were included, and the database was formed by the patients' files and the protocols of implantation. RESULTS: The mean age of patients was 69.5 years. The most frequently reported signs and symptoms before implantation of pace maker were dizzy spells and syncope respectively in 53% and 29.1% of patients. Among the electrocardiographic alterations leading to an indication of pacemaker implantation, atrio-ventricular blocks were the most numerous at 74.4% followed by sinus node disease at 17.1%. Early complications were represented essentially by haematoma and infection of the pocket of pacemaker respectively at 2.9% for each one. After a mean follow up of 6.8 years, 88 patients (45.3%) still free of symptoms. Late complications include lead dislodgement and pacemaker syndrome at 2% for each one. CONCLUSION: The results of our study demonstrates that even the rate of complications following pacemaker implantation is not high, the follow-up of patients should be fast, complete, safe, and clear, and should include sufficient documentation.

Distal radial approach versus conventional radial approach: a comparative study of feasibility and safety.

The distal radial approach (DRA) is suggested to have benefits over the conventional radial approach (CRA) in terms of local complications and comfort of both patient and operator. Therefore, we aimed to compare the feasibility and safety of DRA and CRA in a real life population. We conducted a prospective, observational multicentric trial, including all patients undergoing coronary procedures in September 2019. Patients with impalpable proximal or distal radial pulse were excluded. Thus, the choice of the approach is left to the operator discretion. The primary endpoints were cannulation failure and procedure failure. The secondary endpoints were time of puncture, local complications and radial occlusion assessed by Doppler performed one day after the procedure. We enrolled 177 patients divided into two groups: CRA (n = 95) and DRA (n = 82). Percutaneous intervention was achieved in 37% in CRA group and 34% in DRA group (p = 0.7). Cannulation time was not significantly different between the two sets (p = 0.16). Cannulation failure was significantly higher in DRA group (4.8% vs 2%, p < 0.0008). Successful catheterization was achieved in 98% for the CRA group and in 88% for the DRA group (p = 0.008). Radial artery occlusion, detected by ultrasonography, was found in 3 patients in the CRA group (3.1%) and nobody in the DRA group (p = 0.25). The median diameter of the radial artery diameter was higher in the DRA than the CRA group (2.2 mm vs 2.1 mm; p = 0.007). The distal radial approach is feasible and safe for coronary angiography and interventions, but needs a learning curve.

Epidemiology of thromboembolic and hemorrhagic events in patients with atrial fibrillation under anti-vitamin K.

BACKGROUND: Atrial fibrillation is the most common heart rhythm disorder in the general population. It is associated with increased cardiovascular morbidity and mortality. Given this risk, anticoagulant therapy is vital. AIM: To estimate the incidence of thromboembolic and hemorrhagic events in patients with Atrial fibrillation and treated by oral anticoagulant in a cardiology department. METHODS: We carried out an observational longitudinal study over a period of three years (January 2013 - December 2015) in the external consultation of cardiology of Farhat Hached hospital of Sousse. Pre-established individual records were used as a source and tool for data collection. RESULTS: Overall, 200 patients were eligible. Forty-nine percent had valvular atrial fibrillation. After an average follow-up of 2.6 years, 15 thromboembolic events were noted affecting 13 patients (6.5%), with an incidence of 2.8%. We found a significant association between TTR <50% and the occurrence of stroke and transient ischemic events. Half of the patients had minor bleeding and 9.5% had major bleeding, with an incidence of 3.6%. No significant correlation between these accidents and the TTR was found. In addition, 9.5% of patients were hospitalized for international normalized ratio equilibration. They were mainly patients with valvular atrial fibrillation (72%) (p = 0.002). CONCLUSION: Anticoagulant therapy with anti-vitamin-K remains the most adequate treatment. Thus, a well-conducted treatment ensures a reduction in thromboembolic risk and minimizes the occurrence of hemorrhages inherent to this therapy. Therefore, an assessment of the quality of anticoagulation is essential.

[Study of unexpectedly detected repolarization in a group of black athletes]. / Etude de la repolarisation chez les sportifs de race noire.

INTRODUCTION: Sudden death that occurs during sporting activity affects patients with ignored heart disease. Black athlete's ECG has been little studied and the features of this ethnic group have been discussed. This study aims to study the epidemiological profile and the peculiarities of repolarization of black athletes. METHODS: We conducted a descriptive study of black athletes selected among all the athletes followed in the sectoral Center of Sports Science and Medicine in Sousse over a period of 8 months from March to October 2014. Data were collected using a medical questionnaire. RESULTS: Data on 35 athletes were collected, with a male predominance (94,28%), with an average age of 24,34 years. Four athletes had left ventricular hypertrophy on cardiac ultrasound. There were 8 athletes with atrioventricular block degree I and 8 athletes with electrical type of left ventricular hypertrophy (LVH). ST segment changes were more marked at the level of precordial leads. Five athletes (14.2%) had inverted T waves in V2 and V3. These were the same athletes who ST-segment depression in these same leads. Early repolarization was found in 3 athletes. All these cases had notch signaling. CONCLUSION: Black athletes have quite specific electrical modifications which are important to know. However, our sample is not sufficiently large to certify these results. A comparative study of white athletes would be very interesting.

Management of patients with acute ST-elevation myocardial infarction: Results of the FAST-MI Tunisia Registry.

BACKGROUND: The FAST-MI Tunisia registry was set up by the Tunisian Society of Cardiology and Cardiovascular Surgery to assess the demographic and clinical characteristics, management and hospital outcome of patients with ST-elevation myocardial infarction (STEMI). METHODS: Data for 459 consecutive patients (mean age 60.8 years; 88.5% male) with STEMI, treated in 16 public hospitals (representing 72.2% of public hospitals in Tunisia treating STEMI patients), were collected prospectively.The most common risk factors were smoking (63.6%), hypertension (39.7%), diabetes (32%) and dyslipidaemia (18.2%). RESULTS: Among the 459 patients, 61.8% received reperfusion therapy: 30% with primary percutaneous coronary intervention (PPCI) and 31.8% with intravenous fibrinolysis (IF) (28.6% with pre-hospital thrombolysis). The median time from symptom onset to thrombolysis was 185 min and to PPCI was 358 min. In-hospital mortality was 5.3%. Compared with those managed at regional hospitals, patients managed at interventional university hospitals (n = 357) were more likely to receive reperfusion therapy (52.9% vs. 34.1%; p<0.001), with less IF (28.6% vs. 43.1%; p = 0.002) but more PPCI (37.8% vs. 3.9%; p<0.0001). However, in-hospital mortality in the two types of hospitals was similar (5.3% vs. 5.1%; p = 0.866). CONCLUSIONS: Data from the FAST-MI Tunisia registry show that a pharmaco-invasive strategy of management for STEMI should be promoted in non-interventional regional hospitals.

Design and Rationale of the National Tunisian Registry of Atrial Fibrillation: Protocol for a Prospective, Multicenter Trial.

BACKGROUND: Atrial fibrillation (AF) is an important health problem in Tunisia. A significant change in the epidemiological pattern of heart disease has been seen in the last 3 decades; however, no large prospective multicenter trial reflecting national data has been published so far. Robust data on the contemporary epidemiological profile and management of AF patients in Tunisia are limited. OBJECTIVE: The aim of this study is to analyze, follow, and evaluate patients with AF in a large multicenter nationwide trial. METHODS: A total of 1800 consecutive patients with AF by electrocardiogram, reflecting all populations of all geographical regions of Tunisia, will be included in the study, with the objective of describing the epidemiological pattern of AF. Patients will be officially enrolled in the National Tunisian Registry of Atrial Fibrillation (NATURE-AF) only if an electrocardiogram diagnosis (12-lead, 24-hour Holter, or other electrocardiographic documentation) confirming AF is made. The qualifying episode of AF should have occurred within the last year, and patients do not need to be in AF at the time of enrollment. Patients will be followed for 1 year. Incidence of stroke or transient ischemic attack, thromboembolic events, and cardiovascular death will be recorded as the primary end point, and hemorrhagic accidents, measurement of international normalized ratio, and time in therapeutic range will be recorded as secondary end points. RESULTS: Results will be available at the end of the study; the demographic profile and general risk profile of Tunisian AF patients, frequency of anticoagulation, frequency of effective treatment, and risks of thromboembolism and bleeding will be evaluated according to the current guidelines. Major adverse events will be determined. NATURE-AF will be the largest registry for North African AF patients. CONCLUSIONS: This study would add data and provide a valuable opportunity for real-world clinical epidemiology in North African AF patients with insights into the uptake of contemporary AF management in this developing region. TRIAL REGISTRATION: ClinicalTrials.gov NCT03085576; https://clinicaltrials.gov/ct2/show/NCT03085576 (Archived by WebCite at http://www.webcitation.org/6zN2DN2QX).

Clinical features and prognosis of infective endocarditis in children: Insights from a Tunisian multicentre registry.

BACKGROUND: Infective endocarditis (IE) is a rare condition in the paediatric setting. No data on the epidemiology and prognosis of IE in children are available from North African countries. AIM: To investigate the epidemiological profile and prognosis of IE in children in Tunisia. METHODS: All patients aged≤18 years presenting with IE in three Tunisian tertiary care centres between January 1997 and September 2013 were included. Clinical features and 30-day and 6-month mortality rates were studied. Factors predictive of death at 6-month follow-up were determined. RESULTS: A total of 73 patients were included in the present study. The mean age was 12±4.8 years; 35 (50.7%) patients were male. Rheumatic heart disease (RHD) was the underlying heart disease in 17 (23.3%) cases and IE occurred in a structurally normal heart in 36 (49.3%) cases. Staphylococcus species were isolated in 17 (23.3%) cases. Regarding IE localization, the mitral valve was involved in 28 (38.4%) cases and the aortic valve in 14 (19.2%) cases. Recourse to surgery was reported in 37 (50.7%) cases. Thirty-day and 6-month mortality rates were 13.6% and 19.2%, respectively. Heart failure on admission or during the hospital course, acute renal failure and neurological complications were significantly associated with death at 6-month follow-up in the univariate analysis and after adjustment for age and sex. CONCLUSIONS: In the Tunisian context, IE in children is still characterized by the high prevalence of RHD as an underlying heart disease. Short- and long-term mortality rates remain high. Heart failure, acute renal failure and neurological complications are significantly associated with death at 6-month follow-up.

Echinococcosis of the heart: clinical and echocardiographic features in 12 patients.

UNLABELLED: We describe the clinical and echocardiographic features in 12 patients with hydatid cyst of the heart who were screened between 1985 and 2001. Presenting symptoms have a wide variability but the main symptom was precordial pain. The electrocardiogram was always abnormal and showed T wave inversion in 8 cases, ST depression in 5 cases, incomplete right bundle-branch block in one case and atrial fibrillation in one case. Transthoracic echocardiography and transoesophageal echocardiography constitute the imaging procedure of choice for the diagnosis of cardiac hydatid cyst with a high sensibility, specificity. Computed tomography (CT) was performed in all patients and confirmed the echocardiographic data. MRI was performed in one patient with right atrium hydatid cyst location and confirmed the echocardiographic data. CONCLUSION: In the presence of atypical symptomatology in a patient coming from an endemic area of hydatid cyst, the diagnosis of cardiac echinococcosis is possible.TTE and TEE are the imaging procedure of choice and sufficient for the diagnosis of cardiac hydatid cyst. CT and/or MRI provide more information about the extension of echinococcus disease in other intra- or extrathoracic locations.

[Feasibility of transesophageal echocardiography during balloon mitral valvulotomy]. / Echographie transoesophagienne multiplan durant la dilatation mitrale percutanée.

The purpose of this study was to demonstrate the utility and feasibility of transesophageal echocardiography during percutaneous balloon mitral valvuloplasty (PBMV). 40 patients were included with symptomatic rheumatic mitral valve stenosis with mean age of 31 years. Transoesophageal echocardiographic monitoring allowed an immediate detection of mitral insufficiency in 10 patients. This latter was moderate in eight cases and severe in two cases indicating to stop the procedure. The addition of on-line TEE during PBMV facilitate and confirm the success of the procedure and detect complications.

[Epidemiologic features of myocardial infarction in young patients]. / Caractéristiques épidémiologiques de l'infarctus chez le sujet jeune.

Acute myocardial infarction (AMI) in persons under the age of 45 years is uncommon. To determine the clinical features in young patients presenting with AMI, we include 38 patients with mean age 35 years who survive from myocardial infarction. This disease is almost associated with cardiovascular risk factors, the most common of which are tobacco abuse (90%) and diabetes (20%). The coronary arteries are most often normal (40%) or single vessel (33%). In hospital complications are the same as in the older adult but the prognosis seems to be better.
