Doctor Issues Warning About Heart Failure Sign When Pressing Down on Fingernails
By Health Correspondent
A medical expert has raised awareness about a critical symptom to watch out for when pressing down on fingernails. Dr. Joe Whittington, popularly known as Dr. Joe MD on social media, emphasised the significance of observing pulsating colours of pink and white beneath the nail as a potential indicator of a serious heart condition. In a recent video posted on his Instagram account, he drew attention to Quincke’s sign, which could signify aortic regurgitation, a severe issue that might lead to heart failure or even death if left unattended. Dr. Joe cautioned viewers that detecting this sign could be alarming and prompt medical evaluation.
To test for Quincke’s sign themselves, individuals can press down on the top of their fingernail; the presence of a pulsation shifting between white and pink may suggest an underlying health concern, according to Dr. Joe. He elaborated in his post that Quincke’s sign is a physical indication seen in individuals with aortic regurgitation, a heart condition characterised by blood flowing back into the heart rather than forward due to malfunctioning heart valves, resulting in heightened arterial pulses. Medical professionals utilise this sign as a diagnostic tool for identifying the heart condition.
A case study published in the British Medical Journal in 2021 documented an instance of Quincke’s sign in a 74-year-old man. Additional symptoms such as shortness of breath, weight gain, swelling, and elevated jugular venous pressure ultimately led to the diagnosis of congestive heart failure. The study described Quincke’s pulse as alternating flushing and blanching of the nail bed in sync with the cardiac cycle, often accompanying a wide pulse pressure. While commonly associated with severe aortic valve insufficiency, Quincke’s pulse can also manifest in patients with other conditions like coarctation of the aorta or high-output physiology, signifying high-output heart failure in individuals presenting with heart failure symptoms.
According to the NHS, aside from Quincke’s sign, other warning indications of heart failure include breathlessness, swollen ankles and legs, feeling lightheaded, persistent cough, wheezing, bloated abdomen, fluctuating appetite, weight changes, confusion, rapid heart rate, and irregular heartbeat. It is recommended to consult a GP if experiencing persistent or worsening symptoms of heart failure and to seek immediate medical attention if sudden or severe symptoms occur.
