Keeping blood pressure at safe levels becomes increasingly important as we age, given its association with cardiovascular risks. This article explores effective strategies to manage and lower systolic blood pressure, promoting long-term heart health.

Understanding Systolic Blood Pressure

Systolic blood pressure measures the force exerted against artery walls at the moment the heart muscle contracts. A reading above 135 mmHg is considered elevated, with higher numbers indicating increased risk. Unlike diastolic pressure, which can plateau or decrease in older adults, systolic pressure continues to rise with age due to increasing stiffness of the arteries.

What’s considered healthy in terms of blood pressure changes as we age, though on average having a blood pressure lower than 120 over 80 is seen as low risk.

Systolic/Diastolic

Low risk	120/80
Medium risk	121-134/80-84
High Risk	135+/85+

Lifestyle Modifications

Lifestyle modifications are the healthiest way of lowering systolic blood pressure, enhancing heart health and overall well-being.

Dietary changes: Adopting heart-healthy eating habits can significantly reduce systolic blood pressure. The DASH (Dietary Approaches to Stop Hypertension) diet emphasises fruits, vegetables, whole grains, and lean proteins while limiting salt, red meat, and added sugars. Reducing sodium intake alone could decrease systolic pressure by 5 to 6 mmHg, although this is highly individual and many factors are in play.
Regular physical activity: The Heart and Stroke Foundation of Canada recommends engaging in moderate to vigorous exercise for 30 to 60 minutes to lower systolic blood pressure. Activities like brisk walking, cycling, swimming, and strength training not only reduce pressure but also strengthen the heart and improve arterial health.
Weight management: Excess weight is a significant risk factor for hypertension. Losing even a small percentage of body weight can have a profound impact on blood pressure levels, with each kilogram lost potentially reducing systolic pressure by approximately 1 mmHg.
Limiting alcohol: Alcohol can raise blood pressure by several points, contributing to high blood pressure and stroke. Meanwhile excessive consumption can negate the effects of blood pressure medications. Limiting intake to moderate levels, drinking plenty of water at the same time, or abstaining altogether is advisable.
Quitting smoking: Stopping smoking makes a big difference, as smokers are twice as likely to have a heart attack or stroke, and twice as likely to die from them. The effect worsens the more you smoke, as smokers of more than 25 cigarettes a day are nearly five times more likely to die of heart disease or stroke. Nicotine constricts blood vessels, elevates heart rate, and increases blood pressure. Your chances of having a heart attack start dropping within 24 hours of stopping, while your risk of having a stroke drops to nearly that of a non-smoker within five years.
Stress management: Chronic stress can contribute to elevated systolic blood pressure directly, by raising your heartbeat and creating a ‘fight or flight’ response. Indirectly it can cause unhealthy coping behaviours like overeating or alcohol use. Techniques such as deep breathing, meditation, yoga, and regular physical activity can help manage stress effectively.

Medical Blood Pressure Management

For some individuals, lifestyle changes alone may not be sufficient to achieve target blood pressure levels. In such cases, medication may be necessary.

Antihypertensive medications

There are several classes of blood pressure medications, each working in different ways to lower pressure. Common options include:

Angiotensin converting enzyme (ACE) inhibitors
Beta-blockers
Diuretics
Calcium channel blockers
Angiotensin receptor blockers (ARB).

These medications are generally not without side effects, so your doctor will prescribe medication based on individual health profiles and any pre-existing conditions.

Regular Monitoring and Consultation

Managing systolic blood pressure often requires regular monitoring, both at home and through healthcare providers. This enables timely adjustments to treatment plans and interventions to achieve optimal control.

Complementary Therapies

In addition to conventional strategies, certain complementary approaches may offer additional benefits:

Potassium and magnesium: Increasing the intake of potassium- and magnesium-rich foods can help balance the effects of sodium and support vascular health. Foods like bananas, avocados, spinach, and nuts are excellent sources.
Omega-3 fatty acids: Found in fatty fish, flaxseeds, walnuts, and supplements, omega-3s can improve heart health and potentially lower blood pressure by reducing inflammation and improving arterial function. Around three grams a day will typically lower blood pressure.
Herbal supplements: Some herbal supplements, such as garlic and hawthorn, as well as beetroot juice, have been linked to modest reductions in blood pressure. However, it’s essential to consult with a healthcare provider before starting any supplement, as they can interact with medications.

The Importance of Tailoring to the Individual

It’s crucial to have a personalized approach to blood pressure management. What works for one person may not be as effective for another due to differences in genetics, underlying health conditions, and lifestyle factors. Working closely with healthcare professionals to tailor a comprehensive plan is the best strategy for lowering systolic blood pressure and maintaining cardiovascular health.

You should take a multifaceted approach in lowering systolic blood pressure, by implementing lifestyle modifications, dietary changes, regular physical activity, stress management, and possibly medication. By adopting a holistic and personalized strategy, individuals can effectively manage their blood pressure, reducing the risk of heart disease and enhancing overall well-being.
