Prevention of ischemic stroke in clinical practice: a role of internists and general practitioners

Stroke constitutes a substantial clinical and socio‑economic burden. It is currently the third cause of death worldwide and results in mortality or disability in every third patient at the end of the first year following an acute cerebrovascular event. Although in‑hospital mortality rates in stroke patients have decreased, prevention and cardiovascular risk control remain critical for improving the prognosis and reducing stroke burden worldwide. The definitions of stroke and transient ischemic attack (TIA) have been recently modified following the findings from neuroimaging and thrombolysis research. Both stroke and TIA are recurrent and preventable disorders. Both patients with stroke and those with TIA require prompt clinical workup, risk assessment, and appropriate management because the risk of recurrence, stroke, and coronary events is significant. The 5 most common cardiovascular risk factors (high blood pressure, smoking, abdominal obesity, diet, and lack of physical activity) are responsible for 80% of the cases. Stroke prevention involves lifestyle modification and specific treatment. Secondary prevention of ischemic stroke involves early treatment (antiplatelets and carotid interventions) and long‑term management including lifestyle changes, antihypertensive therapy, antiplatelets, antithrombotic drugs in patients with atrial fibrillation, and the use of statins and other lipid‑lowering drugs. Stroke patients are at risk of depression, dementia, epilepsy, and other complications that also require targeted treatment.
