Secondary prevention of ischemic stroke is mainly directed to lifestyle modifications, treatment of modifiable risk factors, and treatment of specific cause of ischemic stroke.

==Secondary Prevention==
Specific recommendations for prevention strategies often depend on the ischemic stroke/transient ischemic attack subtype. Patients presenting with signs and symptoms of acute stroke will undergo an evaluation tailored to ensure that, when appropriate, they receive reperfusion therapy.
Secondary stroke prevention includes antiplatelet therapy, statins and antihypertensives. Aspirin, clopidogrel, or a combination of aspirin with dipyridamole are first-line options for secondary stroke prevention in the absence of atrial fibrillation. Dual antiplatelet therapy has a benefit in the first three weeks after stroke, but patients should change to a single antiplatelet drug after this time. Anticoagulants are indicated if the patient has atrial fibrillation. Avoid combinations of anticoagulants and antiplatelet drugs.
Patients should be started on statins after an ischaemic stroke. High doses are recommended even if cholesterol concentrations are normal. Antihypertensive drugs are recommended for all patients with systolic blood pressures greater than 140 mmHg. ACE inhibitors, calcium channel blockers and diuretics are first-line options.<ref name="pmid32299593">{{cite journal |vauthors=Diener HC, Hankey GJ |title=Primary and Secondary Prevention of Ischemic Stroke and Cerebral Hemorrhage: JACC Focus Seminar |journal=J Am Coll Cardiol |volume=75 |issue=15 |pages=1804–1818 |date=April 2020 |pmid=32299593 |doi=10.1016/j.jacc.2019.12.072 |url=}}</ref><ref name="pmid21750435">{{cite journal |vauthors=Berge E |title=Should high blood pressure be lowered in the acute stroke? |journal=J Hypertens |volume=29 |issue=8 |pages=1478–9 |date=August 2011 |pmid=21750435 |doi=10.1097/HJH.0b013e32834a019b |url=}}</ref><ref name="pmid31662037">{{cite journal |vauthors=Powers WJ, Rabinstein AA, Ackerson T, Adeoye OM, Bambakidis NC, Becker K, Biller J, B<rown M, Demaerschalk BM, Hoh B, Jauch EC, Kidwell CS, Leslie-Mazwi TM, Ovbiagele B, Scott PA, Sheth KN, Southerland AM, Summers DV, Tirschwell DL |title=Guidelines for the Early Management of Patients With Acute Ischemic Stroke: 2019 Update to the 2018 Guidelines for the Early Management of Acute Ischemic Stroke: A Guideline for Healthcare Professionals From the American Heart Association/American Stroke Association |journal=Stroke |volume=50 |issue=12 |pages=e344–e418 |date=December 2019 |pmid=31662037 |doi=10.1161/STR.0000000000000211 |url=}}</ref><ref name="pmid34024117">{{cite journal |vauthors=Kleindorfer DO, Towfighi A, Chaturvedi S, Cockroft KM, Gutierrez J, Lombardi-Hill D, Kamel H, Kernan WN, Kittner SJ, Leira EC, Lennon O, Meschia JF, Nguyen TN, Pollak PM, Santangeli P, Sharrief AZ, Smith SC, Turan TN, Williams LS |title=2021 Guideline for the Prevention of Stroke in Patients With Stroke and Transient Ischemic Attack: A Guideline From the American Heart Association/American Stroke Association |journal=Stroke |volume=52 |issue=7 |pages=e364–e467 |date=July 2021 |pmid=34024117 |doi=10.1161/STR.0000000000000375 |url=}}</ref>

Treatment of risk factors in patients who have already had strokes (secondary prevention) is also very important as they are at high risk of subsequent events compared with those who have never had a stroke. Medication or [[Pharmacology|drug therapy]] is the most common method of stroke prevention. Aspirin (usually at a low dose of 75 mg) is recommended for the primary and secondary prevention of stroke.  Also see [[Antiplatelet drug]] treatment.  Treating risk factors like [[hypertension]], [[diabetes mellitus]], [[smoking cessation]], control of  [[hypercholesterolemia]], [[physical exercise]], and avoidance of [[Illegal drug trade|illicit drugs]] and excessive alcohol consumption are all recommended ways of reducing the risk of stroke in a patient who already has a history of previous strokes.<ref name="americanheart risk">American Heart Association.

In patients who have strokes due to abnormalities of the heart, such as [[atrial fibrillation]], [[anticoagulation]] with medications such as [[warfarin]] is often necessary for stroke prevention.<ref>American Heart Association. (2007). [http://www.americanheart.org/presenter.jhtml?identifier=4451 Atrial Fibrillation] Americanheart.org. Retrieved on [[January 22]], [[2007]].</ref>
 
Procedures such as [[carotid endarterectomy]] or carotid [[angioplasty]] can be used to remove significant atherosclerotic narrowing (stenosis) of the [[carotid artery]], which supplies blood to the brain. These procedures have been shown to prevent stroke in certain patients, especially where carotid stenosis leads to [[ischemic]] events such as [[transient ischemic attack]]. (The value and role of carotid artery ultrasound scanning in [[Screening (medicine)|screening]] has yet to be established.)

Overview

Secondary prevention of ischemic stroke is mainly directed to lifestyle modifications, treatment of modifiable risk factors, and treatment of specific cause of ischemic stroke.

Secondary Prevention

Specific recommendations for prevention strategies often depend on the ischemic stroke/transient ischemic attack subtype. Patients presenting with signs and symptoms of acute stroke will undergo an evaluation tailored to ensure that, when appropriate, they receive reperfusion therapy. Secondary stroke prevention includes antiplatelet therapy, statins and antihypertensives. Aspirin, clopidogrel, or a combination of aspirin with dipyridamole are first-line options for secondary stroke prevention in the absence of atrial fibrillation. Dual antiplatelet therapy has a benefit in the first three weeks after stroke, but patients should change to a single antiplatelet drug after this time. Anticoagulants are indicated if the patient has atrial fibrillation. Avoid combinations of anticoagulants and antiplatelet drugs. Patients should be started on statins after an ischaemic stroke. High doses are recommended even if cholesterol concentrations are normal. Antihypertensive drugs are recommended for all patients with systolic blood pressures greater than 140 mmHg. ACE inhibitors, calcium channel blockers and diuretics are first-line options.[1][2][3][4]

Life style modification for secondary prevention

Life style modification measures which may help reduce the risk of recurrent stroke and prevent complications may include:

  • Increased physical activity
  • Eating healthy balanced diet
  • Smoking cessation
  • Decreased alcohol intake

Treatment of modifiable risk factors

  • Treatment and maintainence of hypertension, diabetes mellitus and hyperlipidemias[5]
  • Treatment of underlying coronary artery disease
  • Treatment of atrial fibrillation and maintaining anticoagulant prophylaxis in high risk patients
  • Proper management and follow up of genetic hypercoaguable conditions
  • Use of long term antiplatelet therapy such as aspirin, clopidogrel or combination therapy may be used to prevent recurrent ischemic stroke.[5]

Secondary prevention of complications of ischemic stroke

The preventive measures which may help prevent complications of ischemic stroke include:[6][7]

  • Use of intermittent pneumatic compressions and low molecular weight heparin in patients with high risk of thromboembolism
  • There is no prophylaxis for prevention of seizures in patients with ischemic stroke. However, one episode of seizure may mandate the use of antiepileptic medication to prevent recurrence.[6]
  • Proper positioning of patient, and the use of thick feed with the help of nasogastric tube for feeding to prevent aspiration pneumonia in patients with cranial nerve palsies affecting pharyngeal motility and gag reflex[8]
  • Pressure ulcers may be prevented by use of air mattress and regular change in position of patient[7]
