Introduction: Why is secondary stroke prevention so important?
A stroke is a serious medical condition that can lead to long-term impairments and significantly reduce quality of life. However, an equally important task after a stroke is preventing its recurrence. The risk of a recurrent stroke remains high, which is why comprehensive rehabilitation and effective secondary prevention strategies play a key role in long-term recovery and maintaining patient health. These measures are aimed at minimizing risk factors and improving the overall condition of the cardiovascular system.
Blood pressure control: The foundation of secondary prevention
One of the most significant and well-studied risk factors for both the first and recurrent stroke is high blood pressure (BP). Lowering and maintaining BP at a target level is the cornerstone of secondary prevention, especially in patients who have suffered an intracerebral hemorrhage (ICH) [1]. Long-term blood pressure control has been proven to reduce the risk of recurrent stroke and other serious cardiovascular events.
Despite the established benefits, research continues to refine the optimal timing for starting antihypertensive therapy, its intensity, and individual patient response characteristics. For example, a meta-analysis of individual participant data from randomized controlled trials (RECAP-ICH) aims to determine the effectiveness of BP lowering for the secondary prevention of major cardiovascular events in patients with a history of ICH [1]. These studies will help personalize treatment approaches, taking into account the unique characteristics of each patient and various outcomes.
Anticoagulant therapy: Protection against thromboembolism
For patients with non-valvular atrial fibrillation (NVAF), which is a frequent cause of ischemic stroke, anticoagulant therapy is crucial. Direct oral anticoagulants (DOACs) have demonstrated efficacy and safety in preventing recurrent strokes, especially in elderly patients at high risk, as confirmed by real-world clinical practice data [2]. Although randomized clinical trials of DOACs primarily focused on primary prevention in relatively young patients, real-world data fill the gap, demonstrating their benefit for secondary prevention in more vulnerable groups.
A particular challenge is choosing an anticoagulation strategy for patients with atrial fibrillation who have suffered an intracranial hemorrhage (ICH). In such cases, it is necessary to balance the risk of thromboembolism with the risk of recurrent bleeding. A Bayesian network meta-analysis showed that resuming oral anticoagulants (OACs), including new OACs (NOACs) and warfarin, as well as using left atrial appendage occlusion (LAAO), significantly reduces the risk of thromboembolism and all-cause mortality compared to no antithrombotic therapy [3]. Furthermore, LAAO demonstrated an even more pronounced reduction in the risk of thromboembolism and mortality, offering an important alternative for patients for whom long-term medical anticoagulation is contraindicated [3].
Lifestyle and physical activity: The path to recovery
Lifestyle changes and regular physical activity are an integral part of comprehensive rehabilitation and secondary stroke prevention. It has been proven that regular physical exercise is associated with a reduced risk of recurrent stroke [5]. This is especially relevant for patients with symptomatic intracranial atherosclerotic stenosis (sICAS), who have a significantly increased risk of recurrent stroke despite aggressive medical treatment [5].
Traditional gym sessions can be inconvenient or inaccessible for many patients, making it difficult to maintain long-term physical activity. In this regard, structured home-based physical exercise programs are gaining particular importance. The RESIST (Structured Physical Exercise for Symptomatic Intracranial Atherosclerotic Stenosis) study aims to evaluate the efficacy and safety of such a home-based program in reducing the incidence of recurrent strokes in patients with sICAS [5]. This approach promotes sustainable adherence to recommendations and the integration of physical activity into daily life.
The role of patient education and support
Active patient participation in the recovery and prevention process is critical. Structured education and support programs can significantly improve outcomes. For example, the multicenter randomized controlled trial SPRINT INDIA showed that a semi-interactive stroke prevention package, including regular SMS messages, videos, and educational workbooks, contributed to better risk factor control and medication adherence. This led to a reduction in the incidence of recurrent strokes, myocardial infarctions, and mortality in patients who had suffered a subacute stroke [4].
Such programs help patients better understand their condition, the importance of adhering to medication recommendations, and lifestyle changes. They provide the necessary tools and motivation to maintain healthy behaviors, which ultimately improves long-term outcomes and reduces the burden of the disease.
Conclusion: A comprehensive approach to long-term health
Rehabilitation and prevention of recurrent stroke is a multifaceted process that requires a comprehensive approach. It includes strict blood pressure control, adequate anticoagulant therapy for patients with atrial fibrillation, regular physical activity, as well as active patient involvement and education. Modern research continues to expand our knowledge of the most effective strategies, offering new approaches such as home-based exercise programs and digital support tools.
Collaboration between the patient, their family, and a multidisciplinary team of doctors (neurologists, cardiologists, rehabilitation specialists) is the key to successful recovery and risk minimization. Adherence to prescribed treatment and a healthy lifestyle is an investment in long-term health and the prevention of future complications.
