Heart failure is very common, affecting over 64 million people globally, and its prevalence is increasing due to aging populations, with significant numbers in countries like the US (6.2 million) and Australia (over 140,000). It's a chronic condition, often developing in older adults, though it can affect anyone, and it significantly impacts health, leading to high hospitalizations and mortality.
Many people with heart failure can comfortably manage their symptoms and live full, productive lives. “Heart failure is a condition when the heart can't pump enough blood to meet the body's demands,” explains Mandeep Mehra, MD, MBBS, MSc, FRCP (London).
The heart's ability to work decreases with age, even in healthy people. Alcohol use. Drinking too much alcohol may weaken the heart muscle and lead to heart failure. Smoking or using tobacco.
Approximately 6.7 million Americans over 20 years of age have HF, and the prevalence is expected to rise to 8.5 million Americans by 2030. The lifetime risk of HF has increased to 24%; approximately 1 in 4 persons will develop HF in their lifetime.
Heart failure mainly occurs in older people. It usually first arises after the age of 65, and the risk increases with age. More than 10% of people over the age of 70 have heart failure. It is equally common in men and women.
Three early warning signs of heart failure include persistent fatigue/weakness, shortness of breath (especially with activity or lying down), and swelling (edema) in your legs, ankles, and feet, often accompanied by rapid weight gain from fluid buildup, all signaling your heart isn't pumping efficiently enough. Other key indicators are a chronic cough (sometimes with pink mucus) and heart palpitations.
Chronic conditions that damage or weaken the heart muscles are the main cause of heart failure with reduced ejection fraction. For example, coronary heart disease or a heart attack can prevent your heart muscle from getting enough oxygen.
The number one killer in the world is cardiovascular disease (CVD), including heart disease and stroke, responsible for about one-third of all global deaths, claiming nearly 18-20 million lives annually, and remains the leading cause across all regions, according to WHO and World Heart Federation. While COVID-19 caused significant deaths in recent years, CVD has consistently held the top spot for decades, with increases seen globally, especially in younger populations.
Symptoms can develop quickly (acute heart failure) or gradually over weeks or months (chronic heart failure).
Aging. As you age, your heart can weaken and stiffen. People over 65 are more likely to have heart failure.
“Smoking is one of the most harmful things people can do to themselves,” Dr. Maniar says. Blood flow drops, slashing oxygen that fuels the heart, which compensates by spiking blood pressure, heart rate and rhythm, and can lead to hardened and narrowed arteries and blood clots causing cardiovascular disease.
Every 1,000 extra steps daily, up to 10,000, was associated with a 17% reduction in overall risk. These extra daily steps were linked to a 22% reduction in heart failure, 9% reduction in risk of heart attack, and 24% reduction in risk of stroke. Any physical activity is beneficial and the faster you walk, the better.
Frequently observed signs or symptoms, which can occur in isolation or in combination and can thus be used as “red flags” or warning signs include: Shortness of breath (dyspnea) or noticeably reduced exercise capacity. Chest pain (angina pectoris) Swollen feet or ankles (peripheral edema)
It is now not uncommon to see patients living for more than 20 years after a heart failure diagnosis.
Life expectancy can vary depending on factors like age, medical history, and treatment options. On average, life expectancy is about two years after diagnosis of heart failure. In Stage D heart failure, life expectancy is typically less than a year.
Hypertension, or high blood pressure, is often called the "silent killer" for good reason.
Record numbers of men and women globally are now estimated to have reduced kidney function, a new study shows. Figures rose from 378 million people with the disease in 1990 to 788 million in 2023 as the world population grew and aged, making it for the first time a top 10 cause of death worldwide.
Death rate - Country rankings
The average for 2022 based on 196 countries was 8.24 deaths per 1000 people. The highest value was in the Central African Republic: 55.13 deaths per 1000 people and the lowest value was in Qatar: 0.93 deaths per 1000 people.
Stress and heart failure are so closely linked that in some cases, stress can even cause heart failure. For people who already live with heart failure, stress can make it worse. According to Dr.
Yes, a weak heart can often become stronger or significantly improve with consistent effort, involving a doctor-guided plan with regular exercise, a heart-healthy diet (low sodium), medications, stress management, quitting smoking, limiting alcohol, and managing other conditions like high blood pressure or diabetes to improve heart function and quality of life.
Sodium is one of the biggest culprits when it comes to worsening heart failure symptoms. Too much salt can make your body retain fluid, leading to swelling in your legs, ankles or abdomen and putting more strain on your heart. Be sure to check food labels for hidden sodium, and try to limit processed or salty foods.
Main symptoms
fatigue – you may feel tired most of the time and find exercise exhausting. swollen ankles and legs – this is caused by a build-up of fluid (oedema); it may be better in the morning and get worse later in the day. feeling lightheaded and fainting.
Go to your local emergency room or call 9-1-1 if you have: New chest pain or discomfort that's severe, unexpected, and comes with shortness of breath, sweating, nausea, or weakness. A fast heart rate (more than 120-150 beats per minute) -- especially if you are short of breath. Shortness of breath not relieved by rest.
When your heart failure is not very bad, your health care provider may not place you on a fluid restriction. As your heart failure becomes worse, your health care provider may limit your fluids to 6-9 cups (1.5-2 liters) a day. Having other conditions like kidney disease may factor into their decision, too.
