  Introduction: Venous thromboembolic disease (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a frequent and potentially life-threatening condition associated with substantial morbidity, mortality, and healthcare burden. In Algeria, particularly in southern regions, epidemiological and management data remain limited. Objective: To assess the hospital prevalence of VTE in the Internal Medicine Department of Laghouat Mixed Hospital and to describe its epidemiological profile, etiological factors, clinical characteristics, therapeutic management, and in-hospital outcomes over a five-year period (January 1, 2021 to December 31, 2025). Materials and Methods: This was a retrospective descriptive study conducted over five years. Among 5,968 hospitalizations recorded in the Internal Medicine Department, all patients with clinically, biologically, and imaging-confirmed VTE were included. Demographic, risk factor, localization, clinical, etiological, therapeutic, and outcome data were collected from medical records and analyzed descriptively. Results: A total of 267 confirmed VTE cases were identified, corresponding to a hospital prevalence of 4.47%. Cases increased progressively over the study period, with the highest number recorded in 2025 (22.8%). The mean age was 50.8 ± 19.9 years (range: 16–92), with a female predominance (64.8%; sex ratio: 0.54). Regarding anatomical distribution, lower-limb DVT was the most frequent localization (45.5%), followed by pulmonary embolism (17.9%) and cerebral venous thrombosis (14.1%). Isolated DVT accounted for 69.6% of cases, isolated PE for 21.5%, and combined DVT with PE for 8.8%. Less frequent sites included upper-limb, splanchnic, and unusual venous thromboses. Clinically, the most common manifestations were limb edema, warmth, and redness (33.1%), limb pain (17.7%), and dyspnea (9.6%). Etiologically, the main causes were idiopathic or unprovoked VTE (31%), active cancer (17.2%), immobilization, surgery, or trauma (16.7%), and thrombophilia (14.3%). Women were more frequently exposed to hormonal and pregnancy-related factors, whereas men more often presented with cancer-associated or idiopathic events, COVID-19 was found (8.6%) as prothrombotic risk factor. Younger patients were more commonly affected by thrombophilia, cerebral venous thrombosis, and hormonal causes, while older patients predominantly presented with cancer-related VTE and transient acquired risk factors. Therapeutically, initial treatment was mainly based on low-molecular-weight heparin (85.8%). Maintenance therapy was dominated by vitamin K antagonists (53.5%), followed by direct oral anticoagulants (21.4%). Clinical evolution was favorable in 88.8% of patients. The in-hospital complication rate was 9.7%, while mortality reached 7.1%, with the highest rates observed in cancer-associated VTE. Conclusion: VTE is a frequent and heterogeneous condition in internal medicine practice at Laghouat Mixed Hospital, predominantly affecting women and middle-aged adults. Lower-limb DVT remains the most common presentation, while cerebral venous thrombosis and thrombophilia were notable in younger patients. Idiopathic cases remain frequent, whereas cancer represents the main predictor of poor prognosis. LMWH and VKA remain the cornerstone of treatment, while DOAC use is increasing but still limited. Strengthening prevention, early diagnosis, thrombophilia screening in selected patients, and broader access to modern anticoagulation strategies may improve outcomes.

  Introduction: Hypertension is a major public health issue and a frequent reason for emergency department (ED) visits. Epidemiological data regarding hypertension in emergency settings remain limited in Algeria. Objective: This study aimed to determine the prevalence of hypertension in the emergency department and to describe the sociodemographic, clinical, paraclinical, therapeutic, and outcome characteristics of patients admitted to the Emergency Department of Laghouat Mixed Hospital. Methods: We conducted a prospective, descriptive, cross-sectional, single-center study with an analytical component, including all civilian adult patients (>18 years) admitted to the Emergency Department of Laghouat Mixed Hospital (LMH) with hypertension (SBP ≥140 mmHg and/or DBP ≥90 mmHg). All patients presenting with hypertension (BP >140/90 mmHg) were included regardless of the reason for consultation, whether they had uncontrolled hypertension (without acute or subacute target-organ damage) or a hypertensive emergency (with acute or subacute target-organ damage). Following descriptive and comparative statistical analyses using the Chi-square test and Mann–Whitney U test (p < 0.05), sociodemographic, clinical, paraclinical, and outcome characteristics were compared between the two groups. Multivariate logistic regression analysis was performed using SPSS software to identify factors independently associated with the occurrence of hypertensive emergencies. Results: Between November 1, 2025, and April 30, 2026, emergency department records identified 154 civilian patients presenting with hypertension among a total of 16,902 consultations. During the same period, 10,579 patients were registered at the emergency admissions office, including 1,649 hospitalized for medical emergencies. Among the 154 hypertension cases, 74 patients (48.05%; 95% CI: 40.30–55.89%; p = 0.63) presented with a hypertensive emergency (BP ≥140/90 mmHg with at least one acute or subacute target-organ injury), whereas 80 patients (51.94%; 95% CI: 44.11–59.70%; p = 0.63) had uncontrolled hypertension (BP ≥140/90 mmHg, symptomatic or asymptomatic, without target-organ damage), including 48 cases (60%; 95% CI: 24.39–38.87%) of severe uncontrolled hypertension (BP ≥180/110 mmHg, symptomatic or asymptomatic, without target-organ damage). A total of 154 patients with hypertension were identified in the emergency department, of whom 55.84% were male. Hypertension was previously known in 62.33% of patients, while 37.66% were unaware of their hypertensive status before admission. Diabetes mellitus was present in 28.57% of patients, and 70.12% were obese. Patients in the hypertensive emergency (HE) group were significantly older than those in the uncontrolled hypertension (UH) group, with median ages of 65.5 years (IQR = 22) and 53 years (IQR = 18), respectively. Clinically, the main conditions associated with hypertensive emergencies were ischemic stroke (36.48%), acute pulmonary edema (25.67%), and acute kidney injury (21.62%). The predominant clinical manifestations in the HE group were dyspnea (24.32%), motor deficits (31.08%), and chest pain (17.56%). In contrast, patients in the uncontrolled hypertension group mainly presented with headaches (48.75%) and dizziness (33.75%). Multivariate analysis identified advanced age as an independent risk factor for hypertensive emergencies (OR = 1.043; 95% CI: 1.015–1.071; p = 0.002). Likewise, discontinuation of antihypertensive treatment was strongly associated with an increased risk, with an odds ratio of 7.178 (95% CI: 1.638–31.460; p = 0.009). Clinical outcomes were favorable in 85.13% of hypertensive emergency cases and in 96.25% of uncontrolled hypertension cases. In-hospital mortality was low, estimated at 1.35%. Conclusion: The prevalence of hypertension in the emergency department of LMH is comparable to that reported in the literature. However, the relatively high proportion of hypertensive emergencies (48.05%) may be explained by recruitment bias. The study also highlights the lack of standardization in local clinical practices, emphasizing the need to strengthen patient therapeutic education and implement structured, harmonized management protocols to improve overall hypertension care. Finally, the most effective strategy for preventing hypertensive emergencies remains optimal blood pressure control.
