Therapeutic targets achievement in secondary prevention after myocardial infarction in a North African tertiary center.

INTRODUCTION: Despite the demonstrated efficacy of cardiovascular (CV) preventive measures, data from international literature indicate that control of CV risk factors (RF) remains insufficient in very high-risk patients. AIM: This study aimed to assess prevalence of achievement of recommended therapeutic targets for the major and modifiable CVRF 12 months after myocardial infarction (MI). METHODS: From 1st January to 30th April 2023, we collected consecutive patients with type 1 MI who had completed 12 months follow-up. Primary endpoint was prevalence of achievement of all recommended therapeutic targets of low-density lipoprotein cholesterol (LDL-C), diabetes mellitus (DM), arterial hypertension (HTN), and smoking. Targets and treatment goals were defined according to the 2021 European Society of Cardiology guidelines on CV disease prevention. RESULTS: 107 patients, mean age 58.8 ± 8.8 years, 74.8% male, were included. 42 (39.3%) patients had HTN, 50 (46.7%) were diabetics, 77 (72.0%) were smokers and eight (7.5%) had hypercholesterolemia. At 12 months, primary endpoint was achieved in 20 (18.7%) patients. 55 (71.4%) of 77 smoker patients were weaned. Blood pressure was at target in 26 (61.9%) among hypertensive patients. In DM patients, HbA1c target was achieved in 23 (46.0%) of them. 32 patients (29.9%) achieved the goal of LDL-C < 0.55 g/L. CONCLUSIONS: Secondary prevention of CV disease was suboptimal. Less than a fifth of patients achieved treatment target for most major and modifiable risk factors. Improvement in follow-up care and treatment after MI is needed.

Evaluation of stress induced by high-fidelity simulation among anesthesiology and emergency residents: impact of oral debriefing versus video assisted.

AIM: To describe the level of stress in emergency medicine and anesthesia residents during high fidelity simulation sessions and to evaluate the effect of video-assisted debriefing versus no-video assisted debriefing on stress level. METHODS: Prospective randomized study. INCLUSION: emergency medicine and anesthesia residents consenting. Stress was assessed, before and after the training session, by: Blood Pressure (BP), Heart Rate (HR), Simple Numerical Scale (SNS), Scale trait anxiety inventory-YA (STAI-YA). Heart Rate and SNS were measured after debriefing. Residents were randomized into two groups according to the debriefing modality. The design of the simulation session was evaluated by the Simulation design scale (SDS). RESULTS: Thirty-six residents were included. We observed significant increase in the mean HR and mean Systolic BP before briefing and after the scenario respectively from 83.8±9.97 cpm to 101.3±17.84 cpm (p <0.001) and from 112.2±8.3 mmHg to 149.6±16.8 (p <0.001). Mean SNS and mean STAY-YA increased before the briefing and after the scenario respectively from 5±2.11 to 6±1.52 (p=0.004) and from 40±6.6 to 57.8±12.3 (p=0.01). HR and SNS decreased significantly after debriefing regardless of modality. The mean SDS was 84.53±5.8. After scenario, we found significant negative correlation between HR and time needed to initiate symptomatic treatment (r = - 0.449, p = 0.019). CONCLUSION: Learning by simulation of critical situations is associated with significant stress which decreased after debriefing.

Efficacy and safety of two protocols of intravenous insulin therapy in the management of diabetic ketoacidosis.

INTRODUCTION: The correction of insulin deficiency in ketoacidosis DKA is recommended by intravenous (IV) route. Despite abundant literature, the place of the initial bolus of insulin has remained controversial. AIMS: This study was designed to compare the safety and the efficacy of two protocols of intravenous (IV) insulin therapy in the management of DKA admitted in the emergency department. Protocol (A): IV bolus of regular insulin 0.10 UI/Kg followed by a continuous IV infusion of insulin 0.10 UI/kg/H. Protocol (B): No bolus, a continuous IV infusion of regular insulin 0.14 UI/kg/H. METHODS: This was a prospective, not blinded, randomized study including patients aged more than 16 years with moderate to severe DKA. Fluid therapy and potassium replacement were standardized. Patients were randomized into two groups: Bolus-maintenance 0.10 group received protocol (A) and Maintenance 0.14 group received protocol (B). The Primary outcome data was the time to recovery defined by the time to acidosis resolution. The safety was tested by the occurrence of complications: hypoglycemia and hypokalemia. RESULTS: We enrolled 129 consecutive DKA patients. There were no differences between the two groups in clinical and biochemical data on admission, Bolus-maintenance 0.10 group versus Maintenance 0.14 group: mean age (37±18 vs. 38±17 years; p=0.810), Type 1 diabetes n (%): 34(55.7) vs. 34(50); p=0.911, pH (7.14±0.13 vs. 7.15±0.12; p=0.43). There were no differences between the two groups in the outcomes data: Bolus-maintenance 0.10 group versus Maintenance 0.14 group: Time to recovery (17 vs. 16 hours; p=0.76), complication n (%): Hypoglycemia (7(11.5) vs. 10(15.9); p=0.57) and hypokalemia (32(56.1) vs. 30(46.9); p=0.30). CONCLUSION: In the treatment of diabetic ketoacidosis, the two protocols of IV insulin were safe and had a comparable efficiency.

Drug related adverse events due to cardiotropic agents : Epidemiology and prognosis in the emergency department.

INTRODUCTION: The severity of cardiotropic agents overuse is related to the risk of cardiac and hemodynamic life-threatening situations. Toxicity is attributed to their narrow therapeutic spectrum and pharmacodynamic properties. The clinical presentation, however, remains polymorphic and represents a challenge for the emergency physician to relate accountability to the exact agent. AIM: To evaluate epidemiological, clinical and prognostic profile of patients visiting emergency department in whom iatrogeny secondary to cardiotropic use was diagnosed. METHODS: This was a single-center prospective study over 12 months. We included successively all patients aged over 18 years in whom diagnosis of cardiotropic iatrogeny was made. Cardiotropic related drug-induced events were selected after collegial decision making processing. Prognosis was evaluated in terms of severity and mortality at day 30. Univariate analysis was conducted. P<0.05 was significant. RESULTS: We enrolled 51 patients. Median age was 72 years with IQR (25,75) of (62,78). Sex ratio was 0.64. Twenty cases of misuse were identified (39%) with 51% of cases being related to the physician. Accountability of the adverse drug event (ADE) was 51%. The ADE was considered severe in 45% of cases and the death rate on day 30 was 12%. Drug classes were dominated by beta-blockers in 20 patients (39%) and anti-arrhythmic agents (Amiodarone ®) in 18 patients (35%). Beta-blockers were significantly the most incriminated in the occurrence of severe ADE. A double iatrogeny was found in 13 patients (25%). Misuse and physician-related ADE were found to be predictive of the severity of ADE in univariate analysis with respectively: For misuse:(OR brut=22, CI95%=[5.2;93.5] ; p<0.001) and for related physician ADE (OR brut = 3,7 ; CI95%=[1.1;12] ; P= 0.015). Predictive factors of mortality at day 30 in the univariate analysis were: Past renal failure : OR brut 5,8; CI95%[1,3-26,5]; p=0,015 ; misuse with OR brut=16.7, 95% CI=[1.9-143.5], p=0.002 and severe ADE with OR brut=15, 95% CI=[1.75-129], p=0.032. CONCLUSION: This study showed that ADE related to Cardiotropic agents are frequent and remain a serious condition especially in elderly. Betablockers agents were the mostly incriminated therapeutic class in the severity of the clinical condition by its hemodynamic repercussions responsible of a high rate of hospitalizations and mortality. Misuse and physician-related ADE were found to be predictive of the severity. Whereas, occurrence of severe ADE, misuse and past renal failure were predictive of mortality. Moreover, in 51% patients, ADE was preventable and related to the prescription of physician showing the main role of the preventability and the role of the prescriber in the genesis of this severe condition.
