Dr. Dmitry Yaranov, a cardiologist and heart transplant surgeon better known on Instagram as @heart_transplant_doc, recently posted a reminder that prevention is far more powerful than panic-searching symptoms online. In his post titled “Blood tests that catch problems before you waste 5 years Googling your symptoms,” he listed a series of diagnostic tests that can detect silent conditions before they escalate.
Dr. Yaranov, who specializes in advanced heart failure, transplantation, and mechanical circulatory support, has built a large social media following for his easy-to-understand, evidence-based heart health advice. His message this time: don’t rely on search engines to explain fatigue, dizziness, or chest tightness—rely on science.
What your blood can reveal about your future
In the post, Dr. Yaranov divided key blood tests into five major health categories, urging people to bring the checklist to their annual physicals.
Cholesterol and Genetic Risk:
He recommends a Lipid Panel to measure LDL, HDL, and triglycerides; a one-time Lipoprotein(a) test to assess inherited cholesterol risks; and ApoB, a marker that counts all harmful cholesterol particles. Together, these can expose heart disease risks early.
Blood Sugar Control:
For those concerned about diabetes, A1C (a three-month blood sugar average) and fasting glucose remain crucial for identifying prediabetes or insulin resistance before symptoms appear.
Kidney and Metabolic Health:
Tests like creatinine and eGFR evaluate kidney function, while electrolytes such as sodium, potassium, and calcium monitor overall metabolic balance.
Hormones and Inflammation:
Dr. Yaranov advises checking thyroid hormones (TSH, T4) to assess metabolism and rhythm, C-reactive protein (CRP) as an inflammation marker, and vitamin D, which has growing links to cardiovascular health.
Blood Health:
A Complete Blood Count (CBC) and iron and ferritin levels help detect anemia, infection, or oxygen delivery problems—issues often misdiagnosed through internet searches.
Prevention is the real peace of mind
“Bring this list to your annual checkup,” the cardiologist wrote in his post. “Prevention today is peace of mind tomorrow.”
The sentiment resonates in an age when people often lose time, money, and mental peace chasing misleading online diagnoses. Regular lab screenings, experts say, offer a far clearer picture of overall health and can help detect hidden conditions like heart disease, thyroid imbalance, and chronic inflammation long before symptoms worsen.
Dr. Yaranov’s advice is simple yet profound: a single round of routine bloodwork can save years of confusion and anxiety. In an era of endless information and instant answers, his message reminds us that true health literacy begins in the lab—not the search bar.
