Background: Atrial fibrillation (AF) is a common arrhythmia and a major risk factor for ischemic stroke, especially in the elderly patients. Patients with non-valvular AF have a 5-fold excess risk of stroke recurrence and case-fatality rate.Objectives: This study was to evaluate the prevalence of AF and its influence on prognosis in patients with ischemic stroke.Materials & Methods: Total 125 patients with ischaemic stroke were enrolled in this study. Initially they were divided into two groups by ECG - those with AF and those without AF. They were followed up after one month, three months and six months. Comparison was done between the two groups in term of recurrence, mortality and clinical improvement which were assessed by Modified Rankin Score (MRS).Results: Among 125 patients, 22 patients had AF. Those with AF were more frequently male, aged more than 45 years. Recurrence was significantly higher in AF group during one month follow up (p<0.05). The presence of AF was associated with higher mortality in 3 months (p<0.05) and 6 months (p<0.05) follow up. At 3 months follow up clinical deterioration was noted in 9.1% patient with AF compared to 2.9% patients without AF (p<0.01) and at 6 months follow up clinical deterioration was noted in 18.2% patient with AF compared to 4.9% patients without AF (p<0.01).Conclusion: Patients who had an ischemic stroke with accompanying AF had higher mortality, graver stroke severity, more recurrences and poorer functional status than those without AF.KYAMC Journal Vol. 8, No.-2, Jan 2018, Page 8-12
Retropharyngeal abscess (RPA) is a rare entity in infants. There is limited knowledge and literature available about RPA in neonates and young infants owing to its atypical presentation, often causing a diagnostic dilemma to the treating physicians. RPA should always be kept in mind for all infants presenting with upper respiratory tract symptoms. Proper history, meticulous clinical examination and a very high index of suspicion is key to its prompt diagnosis. There is always a risk of airway compromise in neonates and young infants, owing to the narrow airway and an early surgical intervention is mandatory. We hereby present a rare case of RPA in a 35 day old male infant having atypical presentation of stridor and sepsis. Timely radiological evaluation in form of ultrasonography (USG) & contrast enhanced computerized tomography (CECT) neck was instrumental not only in prompt diagnosis but also in immediate decompression drainage of abscess which turned out to be lifesaving.
Atrial fibrillation (AF) is a common arrhythmia and a major risk factor for ischemic stroke, especially in the elderly. Patients with nonvalvular AF have a 5-fold excess risk of stroke. However, population-based data are scarce in patients who have experienced a first-ever ischemic stroke in the presence of AF regarding long-term risk of stroke recurrence and case-fatality rate. Aim of the study is to find out the outcome of ischemic stroke patients with Atrial Fibrillation. It was a descriptive type cross sectional study where 125 diagnosed cases of ischemic stroke were included. Presence of atrial fibrillation was detected by electrocardiogram. They were divided into two groups – those with atrial fibrillation and those without. Comparison was done between the two group in term of recurrence, mortality and clinical improvement. Atrial fibrillation was present in 22 (17.6%) of 125 patients with ischemic stroke. Those with AF were more frequently male, aged 45 years and older. The presence of AF was associated with high 3 months (Χ2 =4.562, df = 1, p<0.05) and 6 months mortality (Χ2 =7.868, df = 1, p<0.05), with a higher stroke recurrence rate within the first 6 months follow-up (22.7% versus 7.8% (<0.05)). At 3 months follow up clinical deterioration was noted in 9.1% patient with atrial fibrillation compared to 2.9% patients who had no arrhythmia(p<0.01) and at 6 months follow up clinical deterioration was noted in 18.2% patient with atrial fibrillation compared to 4.9% patients who had no arrhythmia(p<0.01). Ischemic stroke patients with atrial fibrillation had significant mortality within the study period compared to those without atrial fibrillation. Significant deterioration in clinical outcome was noted in atrial fibrillation group after six months. Recurrence was more in ischemic stroke patients with atrial fibrillation. Multivariate linear regression analysis shows atrial fibrillation as well as CKD, Diabetes mellitus and smoking as independent risk factor for recurrence. In conclusion, patients who had an ischemic stroke with accompanying atrial fibrillation had higher mortality, grave stroke severity, more recurrences and poorer functional status than those without atrial fibrillation.TAJ 2015; 28(2): 1-6
Despite recent advances, only two-third of all strokes can be attributed to known causal risk factors. Homocysteine (tHcy), a sulfur-containing amino acid, is now considered to be an important risk factor for vascular diseases, along with the established risk factors like hyperlipidemia, hypertension, diabetes mellitus, and smoking. Elevated homocysteine levels play a causal role in the pathogenesis of atherosclerosis, thromboembolism and vascular endothelial dysfunction with an increased incidence of ischemic stroke. This study aimed to find out the association of hyperhomocysteinemia with ischemic stroke. A total of 100 subjects were included in this study, 50 were ischemic stroke patients enrolled as case, and 50 were normal healthy individuals enrolled as control. Serum homocysteine level was measured in both case and control groups. The comparison was made in both groups regarding other common risk factors like diabetes mellitus, hypertension, smoking, dyslipidemia, family history, etc. Among 100 patients, 50 had ischemic stroke and 50 were healthy individuals. In this study, out of all patients, abnormal serum homocysteine level was found in 32% of cases and 12% of controls. The mean (±SD) serum homocysteine level was found 16.50±13.86 μmole/L in cases and 9.46±3.49 μmole /L in the control group. Significant (p<0.05) difference was found between the case and the control. The incidence of hyperhomocysteinemia is higher in ischemic stroke cases than that in age-sex-matched healthy controls. In our study, serum homocysteine was high in both younger age group patients (16.65±14.55 μmole/L vs. 9.52±3.19 μmole/L) and older age group patients (16.33±9.87 vs. 9.35±3.97 μmole/L,) in case and control group respectively. Significant (p<0.05) difference was found between the case and the control. Multiple logistic regression analysis showed that abnormal serum homocysteine is an independent risk factor of ischemic stroke. So we conclude that hyperhomocysteinemia is an important and independent risk factor for the development of ischemic stroke. Hypertension and smoking are important contributory to elevated serum homocysteine. TAJ 2021; 34: No-1: 33-39
