Why is prevention important in older age?
With age, the risks of developing many conditions, such as stroke and dementia, increase significantly. However, it is important to understand that most of them can be prevented [1]. Modern medicine actively combats so-called "therapeutic nihilism," where it is assumed that older patients derive less benefit from treatment. On the contrary, studies show that older adults may reap even greater benefits from preventive and therapeutic interventions [1].
Population aging poses new challenges for healthcare, as elderly and very elderly patients often have complex medical needs, multiple comorbidities, and take a large number of medications (polypharmacy) [4]. Common issues such as chronic heart failure, frailty, sarcopenia (loss of muscle mass), cachexia (wasting), and dementia require a comprehensive approach to health management [5].
Healthy Lifestyle: The Foundation of Longevity
Although many cardiovascular disease (CVD) prevention strategies are traditionally targeted at middle-aged individuals, a healthy lifestyle remains critically important for older adults as well. A study conducted among adults aged 75 and older without prior CVD showed that an unhealthy lifestyle significantly increases the risk of myocardial infarction and stroke [3].
Unhealthy lifestyle factors include:
- Smoking
- Alcohol abuse
- Lack of regular physical activity
Each of these factors contributes to an increased risk of CVD. For example, individuals with two or more unhealthy habits had a significantly higher risk of CVD compared to those who led a healthy lifestyle [3]. This emphasizes that it is never too late to start taking care of your health, and simple changes can substantially improve prognoses even in very advanced age.
Prevention of Stroke and Cardiovascular Diseases
Stroke is one of the leading causes of disability and mortality worldwide, especially among older adults [6]. Preventing stroke is the best way to preserve cognitive function in old age [1].
Cholesterol and Blood Pressure Management
Lipid-lowering therapy aimed at reducing cholesterol levels brings significant benefits to older patients, even greater than to younger ones [1]. However, the approach to blood pressure management requires caution. For patients with stiff arteries, a target systolic blood pressure below 120 mmHg may be risky [1]. The decision to initiate lipid-lowering therapy for the primary prevention of CVD in people over 75 is complex and must be made individually, as direct randomized trials in this age group are limited [7]. Nevertheless, meta-analyses of observational data indicate potential benefits regarding mortality reduction [7].
Anticoagulants in Atrial Fibrillation
Atrial fibrillation (AF) is very common among older patients and significantly increases the risk of stroke [2, 4]. Despite this, older individuals with AF often receive suboptimal treatment [2]. Studies show that older patients (over 80 years old) have a higher risk of stroke (according to the CHA₂DS₂-VASc score) yet are less likely to receive oral anticoagulants (OACs) compared to younger patients [2, 8].
Direct oral anticoagulants (DOACs) should be prescribed more frequently to older patients with AF to prevent stroke [1]. Bleeding concerns are often the reason for underprescription; however, studies show that bleeding risk (according to the HAS-BLED score) in older adults is not always significantly higher [2]. Although randomized controlled trials often exclude very elderly patients with comorbidities, newer data, such as the ELDERCARE-AF trial, help fill these gaps and confirm the efficacy of DOACs in this group [4].
The Role of the Microbiome and B Vitamins
Emerging research points to the importance of the interaction between the gut microbiome, age, and renal function, which has significant dietary implications for older adults [1]. Additionally, B vitamins, which help lower homocysteine levels, may play a role in stroke prevention [1]. This opens up new perspectives for dietary recommendations and nutritional support in older age.
Comprehensive Health Approach: The 4Ms Model
For effective prevention and health management in older adults, comprehensive, person-centered approaches are recommended. One such approach is the 4Ms framework of Age-Friendly Health Systems (AFHS) [6]:
- What Matters: Focus on individual patient goals and preferences.
- Medication: Optimization of drug therapy, minimizing polypharmacy.
- Mentation: Assessment and management of cognitive functions, depression, and dementia.
- Mobility: Maintenance and improvement of physical activity and independence.
Nurse-led educational programs based on this model have proven effective in reducing stroke risk and fostering healthy behaviors among older adults [6]. It is also crucial to develop individualized care plans, especially for patients with heart failure and comorbid conditions such as frailty and dementia [5].
Individualized Plan: Dialogue with Your Physician
Most older patients derive significant benefits from timely medical interventions and preventive measures [1]. The key to successful health maintenance is an individualized approach. It is important to consult regularly with a physician to develop a personalized prevention and treatment plan that takes into account your age, comorbidities, lifestyle, and personal preferences. Do not underestimate the capabilities of modern medicine and your own active participation in caring for your health.
