Assessing the effect of high-dose rosuvastatin in elderly patients over 75 with acute coronary syndrome.

BACKGROUNDS AND OBJECTIVE: Statins, inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase, are pivotal in managing hypercholesterolemia and reducing cardiovascular risk. While rosuvastatin demonstrates superior efficacy and tolerability compared to other statins, its safety profile in elderly patients older than 75 years old with acute coronary syndrome (ACS) remains underexplored. So, the objective of this study is to evaluate the frequency of adverse reactions and investigate the efficacy of high-dose rosuvastatin on lipid profiles in elderly patients aged over 75 with ACS. METHODS: In this observational study, 110 consecutive elderly ACS patients attending Modarres Hospital in Tehran, Iran, in 2019 were enrolled. The effects of high-dose rosuvastatin were assessed in elderly patients older than 75 years old by comparison of the adverse effects, lipid profile, cardiac function, and other biomarkers at the baseline and after 6 weeks of rosuvastatin therapy with a dose of 40 mg. RESULTS: Following 6 weeks of treatment, there was a significant reduction in total cholesterol (136.2 ± 24.3 to 115.5 ± 24.0, p = 0.001) and LDL levels (72.6 ± 17.5 to 50.9 ± 18.9, p = 0.001), accompanied by a notable increase in HDL levels (38.3 ± 7.1 to 47.2 ± 7.4, p = 0.001). Cardiac function, as measured by ejection fraction (EF), significantly improved from 43.4 ± 8.8 to 48.5 ± 8.5 (p = 0.001). Adverse effects such as cramps (N = 12, p = 0.001), weakness (N = 28, p = 0.001), and anorexia (N = 12, p = 0.001) were reported but did not warrant discontinuation of therapy. Notably, no cases of jaundice were observed. Two deaths occurred due to major adverse cardiac events (MACE) during the study period, unrelated to stroke or recurrent myocardial infarction. CONCLUSION: Totally, high-dose rosuvastatin therapy effectively improved lipid profiles, cardiac function, and liver enzyme levels in elderly ACS patients, with manageable adverse effects. These findings underscore the importance of rosuvastatin in optimizing cardiovascular health in this vulnerable population.

Unusual presentation of the germinoma: A 26-year-old female.

BACKGROUND: Germinoma is a rare lesion found commonly in the pineal and suprasellar regions of the brain. Clinical presentation mainly involves the location and size of the tumor and the patient age. Endocrine abnormalities are the most common symptom. CASE PRESENTATION: The patient was a 26-year-old Iranian female who suffered from germinoma for a long time and was referred to Loghman Hakim Hospital for amenorrhea, polyuria, and polydipsia. Despite diagnostic challenges, she was finally diagnosed with suprasellar germinoma after endoscopic transsphenoidal surgery, followed by radiotherapy and medical interventions to complement the surgery. CONCLUSION: It is important to be able to diagnose the patient's problem at an early stage based on their history, hormonal profile, laboratory results and radiological view.

Association between Angiotensin-Converting Enzyme Inhibitors and Angiotensin II Receptor Blockers and Mortality in Patients with Hypertension Hospitalized with COVID-19.

Background: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are common hypertension medications. We aimed to investigate the association between treatment with ACEIs/ARBs and disease severity and mortality in patients with hypertension hospitalized for coronavirus disease 2019 (COVID-19). Methods: Information from the medical records of 180 hospitalized patients diagnosed with COVID-19 infection admitted in 2020 to Loghman Hakim Hospital, Tehran, Iran, was collected. Clinical histories, drug therapies, radiological findings, hospital courses, and outcomes were analyzed in all the patients. The demographic and clinical characteristics of the patients were also analyzed, and the percentage of patients with hypertension taking ACEIs/ARBs was compared between survivors and nonsurvivors. Results: The study population consisted of 180 patients at mean±SD age of 67.76±18.72 years. Hypertension was reported in 72 patients (40.0%). Patients with hypertension were older than those without it (mean±SD age =72.35±12.09 y). Among those with hypertension, death occurred in 33 patients (45.8%), of whom 60.6% were men. Fifty-three patients (73.6%) with hypertension were on ACEIs/ARBs. The ACEIs/ARBs group had a significantly lower mortality rate than the non-ACEIs/ARBs group (37.7% vs 68.4%; OR: 0.192; 95% CI: 0.05-0.68; P=0.011). Conclusion: This single-center study found no harmful effects associated with ACEIs/ARBs treatment. Patients on ACEIs/ARBs had a lower rate of mortality and disease severity than the non-ACEIs/ARBs group. Our study supports the current guideline to continue ACEIs/ARBs in patients with hypertension.

Thrombolytic Therapy for Right-Sided Mechanical Pulmonic and Tricuspid Valves: The Largest Survival Analysis to Date.

Data regarding thrombolytic treatment of right-sided mechanical valve thrombosis are almost nonexistent, and all current guidelines arise from very small case series. We retrospectively studied the in-hospital and long-term outcome data of a larger series of patients who had received, from September 2005 through June 2012, thrombolytic therapy for right-sided mechanical pulmonary valve or tricuspid valve thrombosis. We identified 16 patients aged 8-67 years who had undergone thrombolytic therapy for definite thrombotic mechanical valve obstruction in the tricuspid or pulmonary valve position (8 in each position). All study patients except one had subtherapeutic international normalized ratios. The 8 patients with pulmonary mechanical valve thrombosis had a 100% response rate to thrombolytic therapy, and their in-hospital survival rate was also 100%. The 8 patients with tricuspid mechanical valve thrombosis had a 75% response rate to thrombolytic therapy, with an in-hospital survival rate of 87.5%. The one-year survival rate for mechanical valve thrombosis treated with thrombolytic therapy (whether pulmonary or tricuspid) was 87.5%. On the basis of our data, we recommend that thrombolytic therapy remain the first-line therapy for right-sided mechanical valve thrombosis in adults or children-including children with complex congenital heart disease and patients with mechanical pulmonary valve thrombosis. Surgery should be reserved for patients in whom this treatment fails.

Thrombolytic-plus-Anticoagulant Therapy versus Anticoagulant-Alone Therapy in Submassive Pulmonary Thromboembolism (TVASPE Study): A Randomized Clinical Trial.

BACKGROUND: The use of thrombolytic agents in the treatment of hemodynamically stable patients with acute submassive pulmonary embolism (PTE) remains controversial. We, therefore, conducted this study to compare the effect of thrombolytic plus anticoagulation versus anticoagulation alone on early death and adverse outcome following submassive PTE. METHODS: We conducted a study of patients with acute pulmonary embolism and pulmonary hypertension or right ventricular dilatation/dysfunction but without arterial hypotension or shock. The patients were randomly assigned in a single-blind fashion to receive an anticoagulant [Enoxaparin (1 mg/kg twice a day)] plus a thrombolytic [Alteplase (100 mg) or Streptokinase (1500000 u/2 hours)] or an anticoagulant [Enoxaparin (1 mg/kg twice a day)] alone. The primary endpoint was in-hospital death or clinical deterioration requiring an escalation of treatment. The secondary endpoints of the study were major bleeding, pulmonary hypertension, right ventricular dilatation at the end of the first week, and exertional dyspnea at the end of the first month. RESULTS: Of 50 patients enrolled, 25 patients were randomly assigned to receive an anticoagulant plus a thrombolytic and the other 25 patients were given an anticoagulant alone. The incidence of the primary endpoints was significantly higher in the anticoagulant-alone group than in the thrombolytic-plus-anticoagulant group (p value = 0.022). At the time of discharge, pulmonary artery pressure was significantly higher in the anticoagulant-alone group than in the thrombolytic-plus-anticoagulant group (p value = 0.018); however, reduction in the right ventricular size or normalization of the right ventricle showed non-significant differences between the two groups. There was no significant difference regarding the New York Heat Association (NYHA) functional class between the two groups at the end of the first month (p value = 0.213). No fatal bleeding or cerebral bleeding occurred in the patients receiving an anticoagulant plus a thrombolytic. CONCLUSION: When given in conjunction with anticoagulants, thrombolytics may improve the clinical course of stable patients who have acute submassive pulmonary embolism and prevent clinical deterioration.
