The Factors
Heart disease remains the leading cause of death worldwide, but new research offers an encouraging message: nearly 90% of deaths from coronary heart disease are associated with risk factors that can be prevented or managed.
In addition, heart disease is the leading killer of women, yet symptoms and risks are frequently missed. Key issues include atypical heart attack signs, unique female risk factors, and vital prevention steps.
According to a study published in JAMA Cardiology and reported by Medical News Today, making healthier lifestyle choices and proactively managing key health markers has helped save millions of lives over the past three decades.
Coronary Heart Disease Continues to Affect Millions
Researchers estimate that more than 254 million people worldwide were living with coronary artery disease (also known as ischemic heart disease) in 2021.
Coronary heart disease develops when atherosclerotic plaque builds up inside the arteries, reducing blood flow to the heart muscle. Over time, this can lead to serious complications, including:
Heart attack (myocardial infarction)
Arrhythmias
Angina (chest pain)
Heart failure
Stroke
While these statistics are concerning, there is also good news.
A significant portion of the risk factors that contribute to coronary heart disease are modifiable, meaning they can be improved through healthier nutrition, regular exercise, maintaining a healthy body composition, managing blood pressure and blood sugar, and avoiding harmful lifestyle habits.
What the Researchers Studied
Scientists analyzed data from the Global Burden of Disease Study 2023, one of the largest health research projects in the world.
The study evaluated mortality from coronary heart disease and the influence of various risk factors between 1990 and 2023.
Researchers focused on twelve major risk factors, including:
Metabolic Risk Factors
High LDL (“bad”) cholesterol
Elevated systolic blood pressure
High Body Mass Index (BMI)
Elevated fasting blood glucose
Lifestyle Risk Factors
Smoking
Alcohol consumption
Physical inactivity
Environmental Risk Factors
Fine particulate air pollution
Lead exposure
Nearly 90% of Deaths Were Linked to Preventable Factors
Researchers found that approximately 88.7% of coronary heart disease deaths in the United States in 2023 were associated with preventable or manageable risk factors.
The three largest contributors were:
High systolic blood pressure: 47.2%
Poor nutrition: 38.6%
High LDL (“bad”) cholesterol: 28.5%
Lead study author Dr. Gregory Roth, Director of the Cardiovascular Health Metrics Program at the University of Washington, emphasized an important point:
“These risks often cause no symptoms, and many people don’t even know they have them. We want to emphasize that coronary heart disease is preventable, and its risk factors can be modified.”
The Biggest Shift Over the Past 30 Years
One of the most significant findings from the research is that the drivers of heart disease have changed.
While smoking-related deaths have declined considerably, researchers found that excess body weight, obesity, insulin resistance, and elevated blood sugar have become some of the fastest-growing contributors to heart disease.
According to cardiologist Dr. Carlos Alfonso, today’s greatest cardiovascular threats are no longer just smoking—they are:
Overweight and obesity
Type 2 diabetes
Poor metabolic health
This reflects what many healthcare professionals are seeing worldwide: chronic diseases increasingly stem from long-term lifestyle habits.
Are Women Being Affected by This?
Absolutely. Although heart disease has often been perceived as a men’s health issue, it is actually the leading cause of death among women worldwide. Many women don’t realize they are at risk because the warning signs can be more subtle than they are in men, and symptoms are sometimes mistaken for stress, fatigue, or hormonal changes.
Modern lifestyles have also contributed to rising rates of overweight and obesity, insulin resistance, type 2 diabetes, and physical inactivity among women—all major risk factors identified in the research. The encouraging news is that many of these risks can be significantly reduced through consistent strength training, regular cardiovascular activity, a balanced, protein-rich diet, maintaining a healthy body composition, and routine health screenings.
At Fitnello, we believe women’s fitness goes far beyond weight loss—it’s about building a stronger body, improving metabolic health, and protecting your heart so you can live a longer, healthier, and more active life.
What This Means for Your Fitness Journey
At Fitnello, we often remind our members that fitness is about far more than changing how your body looks.
It’s about building a healthier body from the inside out.
Many people focus exclusively on losing weight. However, simply seeing a lower number on the scale doesn’t automatically improve long-term health.
Instead, one of the most important goals should be improving body composition—reducing excess body fat while maintaining or building lean muscle.
Research consistently shows that healthy muscle mass supports:
Better blood sugar regulation
Improved insulin sensitivity
Healthier cholesterol levels
Lower blood pressure
Higher metabolic rate
Reduced inflammation
Better long-term cardiovascular health
Strength training isn’t just for building muscle—it is one of the most powerful tools for protecting your heart.
Nutrition: One of the Most Powerful Medicines
The study identified poor nutrition as one of the leading contributors to heart disease.
A heart-supportive eating pattern generally includes:
Plenty of vegetables and fruits
Lean protein sources
Whole grains
High-fiber foods
Healthy fats
Limited saturated fats
Minimal ultra-processed foods
Reduced added sugars
At Fitnello, we believe nutrition should also be personalized.
There is no one-size-fits-all meal plan. Every person’s metabolism, activity level, body composition, goals, and medical history are different.
That’s why sustainable nutrition focuses on building habits you can maintain—not following restrictive diets that only work temporarily.
Exercise Is One of the Best Preventive Medicines
The researchers also highlighted the importance of regular physical activity.
Current recommendations suggest aiming for at least three hours of physical activity each week, although many health organizations recommend accumulating 150–300 minutes of moderate exercise weekly, along with resistance training.
An effective fitness routine should include:
Strength training to preserve and build muscle
Cardiovascular exercise for heart health
Daily walking and general movement
Mobility and recovery work
Even small improvements in consistency can significantly reduce long-term cardiovascular risk.
Know Your Numbers
Because many cardiovascular risk factors develop silently, experts encourage everyone to “know your numbers.”
Regularly monitor:
Blood pressure
LDL and HDL cholesterol
Triglycerides
Fasting blood glucose
HbA1c
Body composition
Waist circumference
Routine visits with your primary care physician and appropriate health screenings can help identify risks long before symptoms appear.
Small Daily Habits Create Long-Term Health
Heart disease develops over years—not overnight.
Fortunately, the same is true for prevention.
Simple daily habits practiced consistently can dramatically improve long-term health:
Exercise regularly.
Build and maintain lean muscle.
Stay physically active throughout the day.
Eat a balanced, nutrient-dense diet.
Limit highly processed foods and excess sugar.
Don’t smoke.
Maintain a healthy body composition.
Prioritize quality sleep.
Manage stress.
Stay consistent with routine health screenings.
The Fitnello Perspective
At Fitnello, our mission has never been simply helping people lose weight.
Our goal is to help individuals build stronger, healthier bodies that support them for decades—not just for summer.
Every workout completed, every nutritious meal prepared, every walk taken, and every healthy habit practiced contributes to something much greater than appearance. Together, these choices improve metabolic health, strengthen the cardiovascular system, preserve muscle mass, and reduce the risk of chronic disease.
The research is overwhelmingly detailed: many of the factors that contribute to heart disease are within our ability to influence. While genetics and age certainly play a role, the daily decisions we make regarding nutrition, movement, recovery, and lifestyle can have a profound impact on our long-term health.
The best time to start protecting your heart isn’t after a diagnosis—it’s today.
