When a Cold Breaks the Heart: Rising Heart Failure Risk in the Young

A previously healthy 17-year-old student developed severe shortness of breath just a week after recovering from a common cold. Believing it was asthma, his parents reached for an inhaler, but it brought no relief.
As his breathing worsened, they rushed him to the hospital, where imaging revealed an enlarged heart and fluid in his lungs. Doctors diagnosed myocarditis—an inflammation of the heart muscle triggered by the recent viral infection—which had already progressed to heart failure.
Taiwanese cardiologist Dr. Liu Zhongping, who treated the teen, shared this case on NTDTV’s “Health 1+1” to highlight a growing and overlooked threat: heart failure is no longer a disease reserved for older people.
A Silent Crisis: Heart Failure in the Young
Heart failure symptoms can be subtle at first—feeling drained after minimal effort, shortness of breath after a walk, or swollen feet—but they signal serious danger. And more young people are falling victim.Although heart disease remains the leading cause of death in the United States, a Stanford University study published in June found a disturbing trend: While overall cardiovascular mortality has dropped by nearly 66 percent over the past 50 years, deaths from heart failure have risen by 146 percent.
Heart failure-related deaths, particularly among younger adults, have shown a concerning increase. A 2024 study found a significant rise in heart failure mortality for the under-45 age group (906 percent) and the 45-to-64 age group (385 percent) between 1999 and 2021. This trend is often linked to lifestyle factors prevalent in younger populations.
What’s Driving Early-Onset Heart Failure
A growing number of young adults are developing heart failure, driven by lifestyle habits, substance use, and infections that can damage the heart muscle.- Foods high in fat and sugar: Eating large amounts can lead to weight gain and abnormalities in blood sugar, cholesterol, and blood pressure.
- Drug or alcohol abuse: Misuse of illegal substances, prescription medications, or alcohol can contribute to heart failure.
- Viral or bacterial infections: Infections such as COVID-19, the common cold, or the flu can trigger inflammatory responses that cause immunoglobulins to attack heart muscle fibers, leading to necrosis, swelling, and potentially myocarditis, which can impair heart function and cause heart failure.
Why Young People Often Miss the Warning Signs
Young people, often in better overall health, have a higher tolerance for physiological abnormalities than older adults. Consequently, their symptoms might be less pronounced, making it easier to overlook crucial early warning signs.This delayed recognition often means that by the time cardiac issues become apparent, the condition has already progressed significantly, Liu said.
Recognizing Heart Failure Symptoms
It is crucial to stay alert for specific symptoms that can indicate heart failure.1. Shortness of Breath and Poor Sleep
Unlike asthma or general fatigue, heart failure symptoms often worsen when lying down. That’s because:- Lying down increases hydrostatic pressure in the lungs, making it harder to breathe.
- Blood from the lower body flows back to the heart, increasing its workload.
- Fluid may back up into the lungs (pulmonary edema), causing coughing or breathlessness at night.
Liu said that when the human body stays upright, the lungs hang vertically, allowing fluid to settle at the bottom; however, when lying down, the increased pressure in the lungs makes it harder to breathe. Furthermore, blood from the legs tends to flow back to the heart, increasing the pressure on the heart as blood returns. Consequently, heart failure patients often experience poor sleep.
2. Swelling in Both Feet and Legs
In addition to feeling weak during daily walking, patients with heart failure often experience swelling in both feet and ankles. This happens because the weakened heart cannot effectively pump blood back from the extremities, causing blood and fluid to pool in the lower limbs. When blood and fluid accumulate in the limbs, it leads to bilateral swelling (edema)—usually in both legs. If swelling is only in one leg, another cause such as a blood clot may be at play.3. Decreased Urination
As heart failure worsens, kidney function declines, and the body retains fluid. This leads to:- Less frequent urination—for example, only once or twice a day.
- More swelling due to fluid buildup.
- Extra strain on the heart, which has to work harder to pump excess fluid.
Protecting Your Heart With Food
Liu recommends eating more of the following heart-healthy foods:- Nuts: Nonfried and unsalted varieties such as cashews and almonds are rich in unsaturated fatty acids and flavonoids, which are antioxidants that can promote health.
- Dark green vegetables: Rich in dietary fiber and plant nutrients. Fiber supports blood circulation, while vitamins E, K, and C benefit the body. Liu recommends eating vegetables as salads or lightly blanching them to preserve nutrients.
- Fruits: Low-sugar varieties are best for heart health. Blueberries are packed with flavonoids, while grapes contain polyphenol antioxidants and dietary fiber, which help lower blood pressure, reduce blood lipids, and prevent atherosclerosis.
- Fish: A source of polyunsaturated fatty acids. Randomized controlled trials show that omega-3 fatty acid supplementation can decrease cardiac events (such as death, nonfatal heart attacks, and nonfatal strokes) in patients with coronary heart disease and slow atherosclerosis progression. Fish should be cooked at low temperatures; avoid frying, which adds unhealthy fats.
Exercise: A Vital Tool for Heart Health
Physical activity has become a recognized treatment for heart attack recovery or heart failure management. Progressive aerobic exercises, such as brisk walking, jogging , cycling, or swimming, can improve blood circulation, make peripheral blood vessels more elastic, and deliver more oxygen and nutrients. These activities also train heart function, forcing the heart to contract and relax more rapidly, thereby training the heart to work more efficiently.Additionally, resistance training—including sit-ups, push-ups, and weight training—can benefit patients with hypertension, diabetes, metabolic disorders, and even certain heart conditions when properly supervised and planned.
Liu advises consulting with a primary care physician before starting any exercise program. For those with compromised heart function, it’s recommended to have a coach or monitoring equipment present. Regardless of the exercise type, it should be approached gradually, with safety as the priority.
Heart failure is no longer just a disease of older people. As Liu’s teenage patient shows, it can strike unexpectedly—and progress rapidly—if symptoms are ignored. Recognizing the signs, living a healthy lifestyle, and acting early could save a life.
