Dr. Ramzy studies a variety of medical conditions, primarily focusing on cardiovascular diseases and a rare genetic disorder known as prolidase deficiency. His research includes evaluating treatment strategies for heart attacks, examining the complications of peripheral vascular disease, and identifying effective methods for treating complex heart lesions. Additionally, he investigates the genetic causes of prolidase deficiency, which impacts how the body processes collagen, leading to significant health challenges. Through his work, he aims to improve patient outcomes and develop better treatment protocols.
Key findings
In a study on prolidase deficiency, researchers confirmed the diagnosis by identifying a new genetic change, revealing very high levels of proline in the patient's urine.
During the COVID-19 pandemic, the average time to treat heart attack patients after symptoms began increased by 18 minutes, although treatment numbers remained stable.
For patients with coronary bifurcation lesions, using a single stent is effective, while the double-kissing crush technique is preferred for more complex cases.
Among over 18,000 patients with peripheral vascular disease who underwent percutaneous coronary intervention, the 30-day complication rates were 8.6% for PVD patients and 5.8% for non-PVD patients.
Utilizing advanced drug-eluting stents resulted in improved outcomes, with PVD patients experiencing a 10.1% complication rate at 30 days compared to 4.8% for those with traditional stents.

Prolidase deficiency: A novel PEPD missense variant in exon 2.
2023
American journal of medical genetics. Part A
Ido F, Tessier S, Yoder N, Ramzy J, Longo S
Plain English This study looked at a rare genetic disorder called prolidase deficiency, which affects how the body breaks down collagen. Researchers found a new genetic change in a patient that led to symptoms like bone deformities and frequent infections, with testing showing very high levels of proline in the urine, confirming the diagnosis. Understanding this condition better is important for diagnosing and managing patients with similar symptoms.
Who this helps: This helps patients with prolidase deficiency and their doctors.
COVID-19 Pandemic Impact on Percutaneous Coronary Intervention for Acute Coronary Syndromes: An Australian Tertiary Centre Experience.
2022
Heart, lung & circulation
Ramzy J, Martin CA, Burgess S, Gooley R, Zaman S
Plain English This study looked at how the COVID-19 pandemic affected the treatment of heart attacks in Melbourne, Australia, comparing data from before and during the pandemic. Researchers found that while the number of patients receiving a specific heart procedure (called PCI) did not change, the time it took to treat patients after their symptoms started did get longer by an average of 18 minutes during the pandemic, although this time improved as the pandemic progressed. This is important because it shows that even during a major health crisis, heart attack treatments remained consistent, but the delays in treatment time highlight challenges in patient care that need to be addressed.

Percutaneous Coronary Intervention for Coronary Bifurcation Lesions: Latest Evidence.
2020
Current treatment options in cardiovascular medicine
Tan S, Ramzy J, Burgess S, Zaman S
Plain English This study looks at the best ways to treat complex heart issues at points where blood vessels split, known as bifurcation lesions, using a procedure called percutaneous coronary intervention (PCI). It found that for most cases, using a single stent is effective, while a newer technique called double-kissing crush is preferred for tougher cases, especially involving the heart's main artery. These findings matter because they can lead to better treatment outcomes and safer procedures for patients with these heart conditions.
Who this helps: This helps patients with coronary bifurcation lesions and the doctors who treat them.
Outcomes in patients with peripheral vascular disease following percutaneous coronary intervention.

Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions
Ramzy J, Andrianopoulos N, Roberts L, Duffy SJ, Clark D +6 more
Plain English This study looked at patients with peripheral vascular disease (PVD) who underwent a heart procedure called percutaneous coronary intervention (PCI). Among over 18,000 patients, those with PVD faced higher risks of serious complications compared to those without, with 30-day event rates of 8.6% versus 5.8% and 12-month rates of 24.6% versus 13.2%. However, patients with PVD who received advanced drug-eluting stents (DES) had better outcomes, experiencing fewer complications than those with traditional bare-metal stents (10.1% versus 4.8% at 30 days).
Who this helps: This research benefits patients with peripheral vascular disease and their doctors by highlighting the importance of using advanced stents during heart procedures.
The Role of Fractional Flow Reserve and Instantaneous Wave-Free Ratio Measurements in Patients with Acute Coronary Syndrome.
2019
Current cardiology reports
Ihdayhid AR, Koh JS, Ramzy J, Kumar A, Michail M +2 more
Plain English This research paper examined the use of two tests, fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR), to evaluate blood flow in patients with acute coronary syndrome (ACS). The findings indicated that while FFR can help improve outcomes for patients with blocked arteries not directly causing symptoms, there is less certainty about iFR's effectiveness in these cases. Understanding how to best evaluate and treat these patients is crucial because improving blood flow can lead to better health results.
Who this helps: This helps patients with heart conditions, particularly those experiencing acute coronary syndrome.
Ventricular Standstill Following Intravenous Erythromycin and Borderline Hypokalemia.
2016
European journal of case reports in internal medicine
Khan S, Ramzy J, Papachristos D, George N, Fisher L
Plain English This study examined a rare but serious heart condition called ventricular standstill (VS) that occurred in a 49-year-old woman after she received intravenous erythromycin while having low potassium levels. The authors found that VS can happen without symptoms in some cases and stressed the need for careful heart monitoring and electrolyte management during erythromycin treatment, especially since it can prolong the heart's electrical activity and lead to dangerous arrhythmias. This matters because it highlights risks associated with a common antibiotic and promotes safer practices for patients with heart conditions.
Who this helps: This helps doctors and healthcare providers ensure safer treatment for patients receiving intravenous erythromycin, especially those with heart-related issues.

Surgical oncology
Datta RV, Petrelli NJ, Ramzy J
Plain English This study looked at thyroid nodules, which are lumps found in the thyroid gland of about 4-10% of adults, but less than 1% of those nodules turn out to be cancerous. It emphasizes the need for a careful evaluation to determine whether a nodule is harmless or potentially cancerous, using patient history, risk factors, and advanced testing methods to make the right diagnosis. This is important because it helps avoid unnecessary treatment for patients with benign nodules while ensuring those with cancer receive timely care.
Who this helps: Patients with thyroid nodules.
Microsphere determination of cochlear blood flow in chickens.
1987
Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery
Zaluzec D, Ramzy J, Wotring R, Gray L
Plain English This study looked at blood flow in the cochlea (the hearing part of the ear) in chickens by injecting tiny, radioactive particles into their bodies. Researchers found that the average blood flow in the cochlea was about 0.75 microliters per minute, similar to what has been seen in mammals. Interestingly, they noticed that as blood flow to the cochlea increased, blood flow to the brain decreased, which raises important questions about how these systems interact.
Who this helps: This research benefits scientists studying hearing and blood flow in both chickens and mammals.
