The diagonal crease in the earlobe, known as the Frank sign, gained attention after the recent death of influencer Henrique Maderite, victim of a heart attack at the age of 50. Essa physical brand, identified in the influencer’s photos, serves as a possible indicator of cardiovascular problems, as shown by medical studies carried out over the last few decades. Especialistas highlight that the sign does not confirm diseases in itself, but reinforces the need for preventive assessments.

The Frank sign appears as a fold that crosses the earlobe diagonally, from the ear canal to the outer edge. Pesquisas associate its presence with vascular changes similar to those that occur in coronary arteries. In younger people, the mark tends to have greater clinical relevance than in the elderly, where it can appear naturally with aging.

Several cardiovascular risk factors, such as hypertension, diabetes and smoking, increase the likelihood of developing this fold. The association was observed in clinical examinations and autopsies that compared ear tissue with that of arteries affected by atherosclerosis. Profissionais health professionals recommend special attention when the sign appears before the age of 60.

  • Bilateral presence of the fold increases the probability of coronary disease.
  • Combination with other visible markers reinforces the medical alert.
  • Early assessment helps identify arterial blockages before serious events.

Historical origin of the Frank signal

The Frank sign was named after the American doctor Sander Frank, who first described it in 1973 in a scientific publication. At the time, the pulmonologist observed the diagonal fold in patients with coronary artery disease and suggested its possible relationship with heart problems. Desde Therefore, several studies have investigated the brand as a simple and accessible external indicator.

Subsequent research confirmed correlations between the fold in the earlobe and changes in collagen and microcirculation. Essas changes reflect processes similar to those affecting the heart’s arteries, including loss of elasticity and plaque buildup. The initial observation was supported by analyzes involving thousands of participants.

Biological mechanisms involved

The fold appears due to the degeneration of elastic fibers in the ear tissue, a process that occurs in parallel in the arterial walls. Estudos autopsy revealed reduced collagen and changes in small vessels in the lobule region in individuals with advanced atherosclerosis. Essa anatomical similarity explains part of the observed association.

Factors such as accelerated vascular aging contribute to the appearance of the mark. The loss of structural support in the lobe reflects systemic conditions that affect the entire circulatory system. Especialistas point out that deficient microcirculation in the ear acts as a mirror of larger problems in the coronary arteries.

Other folds, such as the anterotragal, also demonstrate a relationship with vascular diseases when present. The combination of multiple creases increases the predictive value for identifying cardiovascular risk. Pesquisas Brazilian women highlight that this association becomes stronger in specific populations.

Scientific studies on the association

Several investigations have compared the presence of the signal with results of cardiac catheterization in patients. The findings indicated a higher frequency of folding in individuals with significant obstructions in the coronary arteries. Meta-analyses brought together data from different countries and confirmed the independent correlation of other factors.

A study carried out at Unesp of Botucatu analyzed hundreds of cases and found a high positive predictive value when the Frank sign appeared next to other folds. Brazilian research reinforced the usefulness of simple clinical observation for initial screening. Resultados similar ones emerged in Asian and European populations.

The specificity of the brand varies depending on the age of the patient. In adults under 60 years of age, its presence substantially increases the likelihood of subclinical coronary disease. Já in the elderly, folding frequently occurs even without diagnosed heart problems.

More recent research has evaluated the signal in conjunction with traditional cardiovascular risk scores. The results showed that the fold contributes to more precise stratification in certain groups. The association remains statistically significant after adjusting for variables such as hypertension and high cholesterol.

Prevalence in different populations

The Frank sign appears in approximately 60% of patients with confirmed coronary artery disease, according to data from large cohorts. In healthy people, the frequency drops to less than 30%, depending on the age group analyzed. Homens present the brand more regularly than women.

Populations with a high incidence of cardiovascular risk factors exhibit high fold percentages. Estudos in type 2 diabetics found an even stronger correlation with retinopathy and other vascular complications. Distribution varies depending on lifestyle habits and genetics.

Identification and visible characteristics

The diagonal fold extends from the tragus to the posterior edge of the lobe at an angle of approximately 45 degrees. Sua depth is classified in degrees, the most pronounced being those that visually divide the lobe into two parts. The bilateral presence reinforces the clinical significance.

Doctors evaluate the brand during routine physical exams. Early identification encourages further investigation even in the absence of symptoms. The fold does not cause discomfort and develops gradually over the years.

Practical medical recommendations

Professionals advise that observation of the sign encourages consultation with a cardiologist or general practitioner. Exames such as electrocardiogram, exercise stress test and cholesterol measurement help clarify the real risk. The assessment considers the set of factors present in the individual.

Lifestyle changes significantly reduce the chances of cardiovascular events. Controle blood pressure, smoking cessation and regular physical activity show proven effectiveness. Prevention remains the main strategy.

  • Maintain a balanced diet low in saturated fats.
  • Carry out annual check-ups after the age of 40.
  • Monitor blood glucose and cholesterol levels periodically.
  • Practice moderate exercise for at least 150 minutes a week.

Limitations and correct interpretations

The Frank sign has low sensitivity, that is, many patients with coronary disease do not present the crease. Sua absence does not exclude cardiovascular risk. On the other hand, high specificity makes the brand useful when present.

Experts warn against isolated interpretations of the fold. The complete clinical context defines appropriate management. The brand works best as a complementary alert to other established indicators.

Recent cases and public attention

The death of influencer Henrique Maderite at the age of 50 brought the topic back to public debate in February 2026. The episode reinforced the importance of simple visible signs.

Other cases documented over the years maintain the relevance of the topic. Brand visibility makes it easier to detect by laypeople and professionals. Increased attention contributes to general awareness.

Cardiovascular prevention involves multiple integrated approaches. The Frank sign represents just one of the many indicators available for medical evaluation. Regular Consultas allow for timely and effective interventions.
