Wearables & Heart Beats: Part 1

The global Wearable Technology Market size was worth about 115.8 (USD billion) in 2021 and is predicted to grow to around 380.5 (USD billion) by 2028
Wearables can measure the pulse and can even tell the heart rhythm. How can wearable technology’s ability to monitor rate and rhythm help in medicine? How accurate are they? Can physicians rely on them in the diagnosis and treatment of abnormal heart rhythms (arrhythmia)?
The European heart rhythm association (EHRA) has recently released a practical guide on the use of digital devices to detect and manage arrhythmia and we are here to review it.
I will not discuss medical devices such as Holter monitors or implantable devices that can deliver therapy such as pacemakers and life vests as they are well established, are prescribed and used by a physician, and fall outside the scope of this episode.

Sleep For Your Heart
Cardio Buzz
08/14/22 • 8 min
A famous quote is, “Happiness is nothing more than getting enough sleep”.
Sleep disturbance is a common condition in modern society, with evidence showing that people sleep on average 1.5 hr less than a century ago. one-third of the general population suffers from sleep-related problems
And now, we better understand the relationship between poor sleep and poor health, especially cardiovascular health. Just a couple of months ago, the American heart association added Sleep to the essential pillars of cardiovascular health.
And in this episode, we will discuss sleep and heart health, what is good sleep, what is bad sleep, what’s the risk of poor sleep, and we will end up with some advice on how to improve your sleep for a stronger heart.
First, is there a relationship between the number of hours slept and CV health?
Yes, we have clear data on this relationship
Sleeping for less than six hours is associated with a 70% increase in mortality
Sleeping 5 hr or less per night had a 2.3-fold greater risk of AMI
Sleeping for less than four hours is associated with a 2.8 times increase in mortality
Sleeping for nine hours or more was also associated with a 70% increase in mortality
The ideal duration of sleep is between seven hours and eight hours because this has been associated with the best survival.
During normal, healthy sleep, blood pressure drops by around 10-20%. This is known as nocturnal dipping, and research highlights its role in cardiovascular health. When we sleep, the blood pressure comes down, and the heart rate also goes down. This helps to unload the circulatory system and give rest to the heart.
Poor sleep, whether from a lack of sleep or sleep disruptions, is associated with non-dipping, meaning that a person’s blood pressure doesn’t go down at night. Studies have found that elevated nighttime blood pressure is related to overall hypertension (high blood pressure). Not only hypertension but sleep disruption is also associated with an increased risk of diabetes, coronary atherosclerosis, and myocardial infarction. Add to that obesity risk; we can remember that we are more likely to feel hungry when we don’t get enough sleep. All these conditions are increased with sleeping less than six hours or with sleeping more than nine hours. It is a U-shaped relation.
We've understood the impact of sleep quantity on health, but what is the impact of poor sleep quality on health?
We also know that difficulty falling asleep, nightmares, easily awakening from sleep, use of sleeping pills, and walking up tired are markers of poor sleep.
Poor sleep quality was associated with subclinical cardiovascular disease and increased risk of cardiovascular disease.
Sleep apnea, where there is airway obstruction resulting in loud snoring and apnea, is a well-established risk for resistant hypertension, heart failure, coronary disease, and atrial fibrillation.
What’s the mechanism linking sleep and poor cardiometabolic health?
There are several potential mechanisms. Data show that a lack of sleep may increase sympathetic nervous system activity the next day; sleep deprivation also results in an inflammatory state and in increased salt intake, elevated cortisol levels, and insulin resistance. These changes all culminate in poor cardiometabolic health resulting in a cascade or a package of cardiovascular diseases.
How to improve your sleep?
First: Identify your ideal sleep duration
The general rule is 7-8 hours of daily sleep. But because this may vary, you can measure your own needed sleep hours this way... Try to get into bed at the time where you fall asleep within about 15 minutes, and wake up without an alarm clock, feeling rested, and having enough energy to carry you through the day. On average, the amount of sleep you get this way is probably the right amount of sleep for you.
The American heart association elected to add sleep duration as an eighth metric to the formal definition of CVH.
