Thanks to Instagram and other such social media platforms, we know a lot about our health than before. In a video, a person presses on his lower leg, and instead of the skin bouncing back smoothly, it shows small pit-like impressions. The caption on the video reads: A Visible Sign Of Congestive Heart Failure.

However, doctors caution that such a finding can be an important clinical sign, often linked to conditions such as peripheral vascular changes or fluid overload. In particular, it may reflect elevated central venous pressure (CVP), a common feature of congestive heart failure (CHF).Medical experts recommend that whenever this sign is seen, it should not be dismissed. Instead, patients should be assessed thoroughly, including checking bilateral pulses, looking for swelling in the legs or feet, and correlating these observations with blood pressure and a full cardiac examination.Understanding Congestive Heart FailureCongestive heart failure, also called simply heart failure, is a long-term condition where the heart cannot pump blood efficiently enough to meet the body’s needs. While the heart is still beating, it struggles to keep up with circulation demands. As a result, blood builds up in other parts of the body, most often in the lungs, legs, and feet.Doctors often describe it with a relatable analogy: imagine a shipping department that is constantly behind schedule. Packages pile up because they cannot be dispatched on time. Similarly, in heart failure, fluid “packages” accumulate in the body, leading to symptoms and complications.Different Types of Heart FailureHeart failure is not a one-size-fits-all condition. It has different forms:Left-sided heart failure, where the left ventricle struggles to pump blood effectively.Right-sided heart failure, which often results from long-standing left-sided failure and leads to blood backing up in veins.High-output heart failure, a rare type where the heart pumps normally but the body demands more blood than it can provide.Right-sided heart failure is particularly linked to distended veins and visible pulsations, as seen in cases where fluid overload is present.How Widespread Is the Problem?Heart failure is alarmingly common. In the United States alone, more than six million people live with the condition, making it the leading cause of hospitalization among those older than 65. With aging populations and rising lifestyle-related diseases such as diabetes and hypertension, the burden of CHF is expected to grow further.Common Symptoms Of Heart FailureCHF can manifest in many ways, some subtle and others unmistakable. Typical symptoms include:Shortness of breath, especially during activity or at nightChest pain and palpitationsFatigue and weaknessSwelling in the ankles, legs, and abdomenWeight gain and frequent nighttime urinationA persistent, dry cough or bloating in the stomachSome patients may experience only mild discomfort, while others face severe, life-limiting symptoms. Importantly, the condition tends to worsen over time if not managed.Causes and Risk FactorsSeveral factors contribute to the development of heart failure, including:Coronary artery disease and heart attacksLong-standing high blood pressureCardiomyopathy, often due to genetics or viral infectionsDiabetes and kidney diseaseObesity, tobacco use, alcohol, or recreational drug useCertain medications, such as chemotherapy drugsRisk increases with age, sedentary lifestyle, poor diet, and family history of heart disease. Left-sided heart failure is the most common trigger for right-sided failure, but lung diseases and other organ issues can also play a role.Potential ComplicationsUnchecked heart failure can lead to serious complications such as irregular heart rhythms, sudden cardiac arrest, valve damage, fluid buildup in the lungs, kidney or liver failure, and malnutrition. These risks make early recognition of clinical signs, such as visible dorsalis pedis pulsation, critically important.Diagnosing Heart FailureDoctors use a combination of medical history, physical examinations, and diagnostic tests to confirm CHF. They typically ask about family history, lifestyle habits, medication use, and other medical conditions. Key tests include echocardiograms, ECGs, chest X-rays, MRIs, CT scans, stress tests, and blood work. In some cases, genetic testing may also be used.Stages of Heart FailureHeart failure is classified into four stages (A to D):Stage A: High risk but no symptoms, often due to conditions like hypertension or diabetes.Stage B: Structural heart problems but no outward symptoms.Stage C: Clear symptoms alongside a confirmed diagnosis.Stage D: Advanced heart failure with severe, treatment-resistant symptoms.
