Diabetes Meets Sudden Cardiac Arrest

Author: Marcy Burnham, RN

The chronic condition Diabetes mellitus—encompassing both type 1 and type 2—has become a massive global health challenge:

  • According to the International Diabetes Federation (IDF), about 1 in 9 adults (20-79 years) are living with diabetes worldwide.
  • It’s estimated that 589 million adults are living with diabetes globally, and that number is projected to rise to 853 million by 2050.
  • The condition comes in two major types:
    • Type 1 diabetes: Autoimmune destruction of insulin-producing cells; less common.
    • Type 2 diabetes: Insulin resistance or inadequate insulin production; accounts for the vast majority of cases.
  • Many remain undiagnosed: For example, IDF estimates that about 252 million adults are living with diabetes but do not know it.
  • Diabetes isn’t just about high blood sugar—it’s a major risk factor for damage to the heart, blood vessels, kidneys, nerves and eyes.

Diabetes is both widespread and highly consequential for long-term health.

Sudden cardiac arrest (SCA) is an abrupt electrical malfunction of the heart leading to the heart stopping its effective pumping activity:

  • SCA is not the same as a typical heart attack (blocked artery) though a heart attack can trigger SCA.
  • It often happens without warning: sudden collapse, no pulse, no breathing. Key risk factors include heart disease, prior heart attack, high blood pressure or cholesterol, smoking, obesity, sedentary lifestyle—and yes, diabetes.

When diabetes and heart health risks overlap, the potential for SCA increases. Diabetes contributes to heart and vessel damage, promotes arrhythmias, and often coexists with other risk factors (e.g., high blood pressure, obesity). Addressing diabetes isn’t just about sugar control—it’s fundamentally about protecting the heart.

Below are five prominent mechanisms by which SCA risk rises (especially in people with diabetes or cardiovascular risk), followed by actionable prevention strategies.

1. Vascular and Heart Muscle Damage

  • Control blood sugar, blood pressure and lipids.
  • Regular check-ups with a cardiologist if you have diabetes.
  • Avoid smoking; limit alcohol.
  • Use medications as prescribed (statins, antihypertensives).

2. Arrhythmia Risk

  • Get periodic ECGs or echocardiograms when recommended.
  • Manage underlying heart disease.
  • In high-risk cases, evaluation for devices (e.g., implantable cardioverter defibrillator

3. Uncontrolled Diabetes and Metabolic Stress

  • For Type 2: prioritize healthy lifestyle (diet, exercise, weight management).
  • For Type 1: maintain consistent insulin therapy and glucose monitoring.
  • Regular review of treatment plan and complication screening (kidneys, eyes, heart).

4. Coexisting Risk Factors

  • Aim for at least 150 minutes/week of moderate physical activity. DMC Hospital
  • Adopt a heart-healthy diet (rich in fruits/vegetables, lean protein, whole grains; low in processed foods/sugars).
  • Smoking cessation and avoidance of second-hand smoke.

5. Lack of Awareness/Late Detection

  • Regular screening for diabetes, especially in high-risk groups (family history, overweight, age>45, etc).
  • Routine cardiovascular risk assessment (blood pressure, lipid profile, ECG).
  • Understand warning signs of heart trouble (palpitations, fainting, chest discomfort) and act fast—call 911 if someone collapses suddenly

The convergence of diabetes and sudden cardiac arrest risk underscores the interconnected nature of metabolic and cardiovascular health. While the numbers can feel daunting—hundreds of millions living with diabetes, and SCA being a silent killer—the good news is: many of the risk factors are treatable.

By proactively managing diabetes (whether type 1 or type 2), controlling associated cardiovascular risks, living a heart-healthy lifestyle, and staying alert for warning signs, we tilt the odds in favor of prevention rather than reaction.

Utility Crews Need AEDs and CPR Training

Every day, utility workers head into the field to keep our communities running—restoring power in storms, repairing water lines, or maintaining gas infrastructure. It’s dangerous, physical work, often done in isolated locations or under extreme conditions.

But amid all the safety procedures, harness checks, and electrical lockouts, one simple fact often goes overlooked: the greatest life-threatening emergency a crew might face isn’t always external. It could happen to one of their own.

Cardiac arrest can strike without warning—on the job site, in the truck, or even while taking a lunch break. It doesn’t matter how fit or experienced someone is. When it happens, every second counts.

For every minute without CPR or defibrillation, the chance of survival drops by about 10%. After just 5 minutes, brain damage begins. After 10, survival is rare. Waiting for EMS isn’t always an option—especially when crews are miles from town or working in storm-damaged areas.

That’s why utility companies need to think beyond traditional safety measures. They need AEDs in their vehicles and employees trained in CPR—not just for the public, but for their own teammates.

An Automated External Defibrillator (AED) is a small, portable device that can restart a heart in sudden cardiac arrest. It analyzes heart rhythms and delivers a shock if needed—all with clear voice prompts. Anyone can use one safely.

For utility companies, having AEDs in fleet vehicles is a logical, lifesaving step:

  • Crews are mobile. They’re constantly on the move, often working far from immediate help.

  • They’re exposed to physical stress. Long hours, heavy labor, extreme temperatures, and adrenaline can all strain the heart.

  • They look out for each other. If a coworker goes down, having an AED nearby can mean the difference between tragedy and survival.

A few hundred dollars and some simple maintenance could save a priceless life.

When a colleague collapses, panic is natural—but knowledge conquers fear. Performing hands-only CPR immediately keeps oxygen-rich blood flowing to the brain and organs until an AED can be used or EMS arrives.

The truth is stark: bystander CPR can double or triple survival chances. When a crew member knows how to perform CPR, they become their partner’s best chance at life.

Training every field worker in CPR ensures no one stands helpless in an emergency. It’s a simple investment that builds confidence, teamwork, and a safety culture rooted in real-world preparedness.

Utility companies are built on the principles of reliability, responsibility, and community service. That same commitment should extend inward—to protecting the people who make the work possible.

Equipping vehicles with AEDs and training every employee in CPR:

  • Protects workers in the field from the unexpected.

  • Demonstrates leadership and compassion for the workforce.

  • Builds stronger, safer crews who know how to react when seconds matter.

  • Strengthens community trust—because people notice when companies put safety first.

This isn’t just about compliance or optics—it’s about ensuring every worker goes home safe, every day.

Across the country, there are stories of lives saved because someone nearby had an AED and knew CPR—coworkers reviving coworkers, linemen saving teammates, and crews who turned tragedy into triumph.

Don’t wait for a wake-up call to act. Make AEDs and CPR training a standard part of your utility fleet and culture.

Because when it’s your partner, your friend, or your crew leader who suddenly collapses, you’ll want to know you did everything possible to save them.

Utility work is built on trust—the trust that your crew has your back no matter what. Adding AEDs to every vehicle and making CPR a universal skill honors that bond.  In an emergency, you might not have time to wait for help.  But with the right tools and training, you can be the help.
