SmartBP's Heart Tracker: Your Partner for Heart Health and Hypertension Management

When it comes to maintaining a healthy heart and managing hypertension, staying informed about your body’s vital metrics is key. The SmartBP ® app, a trusted tool for managing blood pressure, now features the innovative Heart Tracker, offering deeper insights into your heart rate (HR) and heart rate variability (HRV). Together with the Cardiobyte ® app, which focuses on fitness heart rate zones and activity tracking, you can now take your cardiovascular and fitness health to the next level.

Let’s dive into how these apps work together to provide a comprehensive view of your heart health and why understanding HR and HRV is essential.

What is Heart Rate and Why Should You Track It?

Understanding Heart Rate (HR)

Your heart beats to pump blood throughout your body. Heart rate measures the number of times your heart beats per minute (BPM). It fluctuates based on your physical activity, stress, emotions, and fitness levels:

• Resting heart rate: Typically between 60–100 BPM for most adults. (Mayo Clinic, 2024).
• Active heart rate: Varies based on exercise intensity, reflecting how hard your heart is working during physical activity. Your maximum heart rate is calculated as 220 minus your age. For moderate to vigorous exercise, your target heart rate typically ranges from 50% to 85% of your maximum heart rate (American Heart Association, 2023).

Why Heart Rate Matters

Tracking your heart rate provides crucial insights into your cardiovascular health. For example:

• A resting heart rate over 100 may indicate tachycardia, but it isn’t always problematic. It could be a temporary symptom of another condition. A consistently elevated resting heart rate may indicate stress, cardiovascular strain, or medication use.
• A resting heart rate below 60 may indicate bradycardia but isn’t always a concern. It could result from medications like beta blockers or occur during sleep. Athletes often have lower heart rates because their strong heart muscles work more efficiently.
• An optimal heart rate during exercise ensures you're working in the right fitness zone (fat burn, cardio, or anaerobic). A lower rate is common among athletes or those with excellent cardiovascular health

According to the American Heart Association (2023), research shows that a higher resting heart rate is associated with lower physical fitness, higher blood pressure, and increased body weight. Regular exercise and heart rate monitoring help you understand your baseline and detect sudden changes early, allowing you to take prompt action. Additionally, monitoring your ECG when you notice these changes can help you identify serious conditions like atrial fibrillation and other arrhythmia that can lead to heart attack or stroke.

Heart Rate Variability (HRV): What It Is and Why It Matters

What is HRV?

Heart Rate Variability (HRV) measures the variation in time between consecutive heartbeats, reflecting your autonomic nervous system's activity. Factors influencing HRV include age, fitness level, sleep, stress, and chronic conditions. Monitoring HRV can help assess overall health, recovery, and stress management, making it a useful tool for optimizing well-being.:

• High HRV: Indicates resilience, adaptability and a healthy cardiovascular system.
• Low HRV: Suggests stress, fatigue, poor recovery, underlying health issues or an increased risk of cardiovascular disease

HRV and Stress Management

Chronic stress can raise your heart rate and reduce HRV, making it harder for your body to recover. With SmartBP's heart rate variability tracking, you can become aware of your typical baseline and monitor changes in your HRV which will help you:

• Identify stress patterns.
• Implement stress-reduction techniques like meditation, better sleep, and physical activity.

The Cleveland Clinic emphasizes that managing stress can lower the risk of hypertension and heart disease.

Understanding the Relationship Between Heart Rate and Blood Pressure

Heart rate and blood pressure are two critical metrics for assessing cardiovascular health, yet their relationship is often misunderstood. Heart rate refers to the number of times the heart beats per minute to supply blood to the rest of the body, while blood pressure measures the force exerted by blood on the walls of the blood vessels. Although both play vital roles in circulating nutrients, oxygen, and energy throughout the body, they function independently.

Independent Mechanisms

Heart rate is primarily regulated by electrical signals sent to the heart via the autonomic nervous system, specifically the sympathetic and parasympathetic branches. In contrast, blood pressure is influenced by the mechanical action of the heart pumping blood, vascular resistance, and blood volume. As a result, a faster heart rate doesn’t always equate to higher blood pressure, and vice versa. For instance, during exercise, heart rate increases to meet oxygen demand, while blood pressure may remain relatively stable depending on vascular adjustments (Verywell Health).

Correlation of Blood Pressure with Heart Rate, Variability and Risk

Despite their independent regulation, studies suggest that fluctuations in heart rate and blood pressure can provide valuable insights into cardiovascular risk:

1. Day-to-Day Variability: Research has shown a strong link between blood pressure variability and stroke mortality, and between heart rate variability and cardiac mortality (Kikuya et al., 2000).
2. Stress: Chronic work stress increases heart rate, systolic blood pressure, and lowers vagal tone, contributing to a higher risk of mild hypertension (Vrijkotte et al., 2000).
3. ‍Heart Rate as a Risk Factor: Elevated resting heart rate is recognized as a potential risk factor for cardiovascular diseases, independent of blood pressure levels. This is supported by studies showing that faster heart rates can strain the cardiovascular system over time, increasing the likelihood of adverse outcomes (Palatini, 1997).

Treating Elevated Heart Rate in Hypertension

Elevated heart rate (HR) is linked to higher blood pressure (BP) and increased cardiovascular risk, but it is not commonly targeted in hypertension treatment. While HR correlates positively with peripheral BP, it inversely affects central BP, a key cardiovascular risk factor. Current evidence does not clearly support HR reduction as a standalone strategy, and some HR-lowering drugs may have limited impact on central BP. Further research is needed to clarify HR's role in hypertension management and its potential benefits. (Reule & Drawz, 2012).

How SmartBP's Heart Rate Tracker Works

The Heart Tracker integrates seamlessly with wearable devices like smartwatches, through Apple Health, allowing you to track your HR and HRV. This data is displayed in easy-to-understand graphs and trends, empowering users to:

• Monitor daily fluctuations in heart rate.
• Track weekly trends to identify lifestyle factors impacting your heart health.
• Detect irregular patterns that could indicate potential health issues.

By visualizing your heart health, SmartBP helps you make informed decisions to improve your lifestyle.

Why Monitoring Weekly and Daily Trends Matters

Your heart rate changes throughout the day depending on your activities and environment. Tracking daily trends can help answer critical questions:

• Does your heart rate spike during stressful situations?
• Are you recovering properly after exercise?
• Do you notice unusual patterns in your resting heart rate?
• What zones are you hitting in your workouts?

By identifying these patterns, you can make immediate adjustments to better manage stress, improve sleep, or enhance your exercise routine.
