Retrospective analysis of stroke and its risk factors at Nepal Medical College Teaching Hospital.

Stroke is a major public health burden worldwide and is responsible for a large proportion of disability; and ranks third in the causation of morbidity and mortality. This disease although regarded as a disease of old age, it is not uncommon in younger population in developing countries.. A retrospective study of cerebro-vascular accidents (stroke) managed at Department of Medicine, Nepal Medical College Teaching Hospital during the period of 1st April 2000 to 31st March 2005 was done to study demographics and risk factors. Cases of TIA were not included in the final analysis of the data due to uncertainty of diagnosis and lack of imaging (CT scan). The collected data was analyzed using data analysis software SPSS (version 12). We identified 72 cases of stroke excluding TIA. The mean age at which patients in this study experienced their first ever stroke was 61.7 yrs (SD 14.9 yrs). The commonest presenting complaints in our study population were weakness of limbs (90.3%), slurring of speech (33.3%), altered mental status (29.8%), deviation of angle of mouth and headache (22.2%) each and urinary incontinence (13.9%). Vomiting, dizziness, fever, personality changes, seizure, tingling sensation of limbs were uncommon clinical presentation and were present in 15.28% of cases. Risk factors were smoking (58.3%), hypertension (47.2%), alcohol (41.4%), atrial fibrillation (12.5%) and diabetes mellitus (11.1%). To conclude, stroke in countries like Nepal is a public health problem. The clinical presentations and risk factors are in agreement with other studies. The low mean age of stroke patient reflects demographic feature of this region.

ECG findings in elderly.

There are not sufficient studies on ECG in elderly population in Nepal. This study attempts to evaluate the findings of ECG in elderly population in Nepal. ECG recordings from 171 apparently healthy geriatric subjects aged above 60 yrs (Mean age 70.66 +/- 7.14 yrs) from different geriatric homes were studied. The ECG was entirely normal in 38.6% of the study population. The major abnormalities were sinus bradycardia in 31 (18.1%) subjects, LVH in 25 (14.6%) subjects, premature supraventricular beats in 16 (9.4%) subjects, T wave changes in 11 (6.4%) subjects and right bundle branch block 16 (9.4%) subjects. Poor R wave progression in precordial leads in 9 (5.3%) subjects and right atrial overload in 4 (2.4%) were other common findings. More than one third of the elderly population in our study had entirely normal ECG. Majority of the abnormalities found in this study were very minor. These observations are important for the future studies evaluating healthy ageing in this region.
