Thailand Medical: A new long-term study from Thailand is shedding light on a little-understood but potentially deadly aspect of early systemic sclerosis, also known as scleroderma—a disease that hardens the skin and can damage internal organs. Researchers have now identified key warning signs that may help doctors predict which patients are at risk of serious vascular complications such as heart disease, stroke, and tissue death in the fingers.
Early warning signs in scleroderma patients may help prevent deadly vascular complications
Understanding a Silent Threat
Systemic sclerosis is known for causing blood vessel damage, but until now, there has been limited data on how early these complications begin and what drives them. The new
Thailand Medical research followed patients over many years and found that even in the early stages of the disease, dangerous vascular problems can develop surprisingly quickly.
The study tracked 146 patients treated at Maharaj Nakorn Chiang Mai Hospital in Thailand, with researchers from the Faculty of Medicine, Chiang Mai University, including experts from the Division of Rheumatology, Division of Cardiology, and Division of Diagnostic Radiology.
What the Study Found
Over an average follow-up period of eight years, about 11.6 percent of patients developed ischemic vascular complications. These included coronary artery disease, ischemic stroke, and digital gangrene - a severe condition where finger tissue dies due to lack of blood supply.
According to the data presented in the study, the median time for these complications to appear was just two years after the first symptoms unrelated to Raynaud’s phenomenon.
The findings show that although these complications are not extremely common, they occur early and can significantly worsen survival outcomes.
Key Warning Signs Identified
Researchers discovered several strong predictors that could signal higher risk. These include:
-The presence of digital ulcers (painful sores on fingers)
-Traumatic ulcers caused by minor injuries
-Reduced heart pumping function (LVEF below 50 percent)
-Elevated levels of a cardiac biomarker called pro-BNP
-Atrial fibrillation, an irregular heart rhythm
This Medical News report highlights that these factors are not just minor clinical details - they are critical warning signals that the body’s blood vessels are already under serious stress.
Interestingly, traditional cardiovascular risks such as diabetes, obesity, and smoking were not significantly different between patients who developed complications and those who did not. This suggests that the disease itself plays a major role in damaging blood vessels.
Breaking Down the Risks

The study also examined each complication separately. For heart disease, high cholesterol and elevated pro-BNP levels stood out as major contributors. For stroke, atrial fibrillation emerged as a particularly powerful risk factor, increasing the likelihood dramatically.
Digital gangrene, one of the most alarming complications, was strongly linked to pre-existing finger ulcers and poor heart function. Patients with these signs were far more likely to develop severe tissue damage.
Impact on Survival
One of the most concerning findings was the effect on survival. Patients who developed vascular complications had significantly higher death rates compared to those who did not. More than half of those with complications died during the study period, compared to less than a third of those without.
Even though some results did not reach strict statistical significance, the trend was clear - vascular complications in early systemic sclerosis are dangerous and often life-threatening.
Why This Matters
This study is one of the first to closely follow early-stage patients over many years, offering valuable insights into how the disease progresses. It shows that doctors should not wait for severe symptoms before acting. Instead, early monitoring of heart function, blood markers, and even small skin ulcers could make a critical difference.
Conclusion
The findings from this Thai cohort study reveal that while ischemic vascular complications in early systemic sclerosis may not affect every patient, they carry serious consequences when they do occur. The identification of clear risk factors such as digital ulcers, heart dysfunction, elevated pro-BNP levels, and atrial fibrillation provides clinicians with valuable tools to detect danger early. These insights emphasize the need for proactive screening and personalized care strategies. Early intervention could potentially reduce complications and improve survival outcomes, making this research an important step forward in managing a complex and often unpredictable disease.
The study findings were published in the peer reviewed Journal of Clinical Medicine.
