The success of Drug-Coated Balloon (DCB) angioplasty hinges critically on effectively preventing coronary artery recoil, an acute elastic response that threatens procedural efficacy and long-term vessel patency. While technical approaches remain foundational, emerging evidence reveals dietary intervention as a pivotal, yet significantly undervalued strategy. At Bethsaida Hospital, under the visionary leadership of Prof. Dasaad Mulijono, implementing a whole-food, plant-based dietary regimen before DCB procedures has profoundly decreased acute recoil incidence. Remarkably, this dietary approach has yielded a restenosis rate of only 2%, marking one of the lowest recorded outcomes in Indonesia. Such compelling data underscore the potential of dietary modification, particularly emphasizing foods rich in Nitric Oxide (NO) precursors and antioxidants, as a potentially revolutionary adjunctive therapy in interventional cardiology. Given these provocative findings, further rigorous investigations are urgently required to confirm the robustness and broad applicability of these transformative dietary interventions.
DCB angioplasty represents an innovative, minimally invasive procedure increasingly adopted in contemporary cardiovascular care for the treatment of Coronary Artery Disease (CAD). At the same time, DCB techniques offer substantial advantages, including reduced stent-related complications and favourable long-term outcomes; however, challenges such as acute elastic recoil persist, compromising procedural success and vessel patency. Acute recoil refers to the immediate, elastic response of the arterial wall following balloon deflation, which can potentially lead to suboptimal lumen expansion and an increased risk of restenosis [1-7].
Traditionally, procedural and pharmacological measures—such as meticulous lesion preparation, optimal balloon sizing, and the use of adjunctive pharmacotherapy—have dominated clinical strategies aimed at preventing recoil [8-10]. However, recent clinical insights suggest that dietary intervention, especially the incorporation of foods rich in NO precursors and antioxidants, presents an innovative and powerful approach to mitigating this issue. NO, a crucial vasodilator produced endogenously within endothelial cells, facilitates arterial relaxation, decreases vascular resistance, and contributes significantly to arterial compliance. Enhancing endothelial NO bioavailability through diet can condition coronary vessels, improving their responsiveness to angioplasty-induced mechanical stress [11-18].
At Bethsaida Hospital, pioneering efforts led by Prof. Dasaad Mulijono have integrated comprehensive, Whole-Food Plant-Based Diet (WFPBD) interventions as an integral part of patient preparation for DCB angioplasty. Preliminary outcomes from this strategy have demonstrated remarkable success, significantly reducing acute recoil episodes and achieving one of the lowest restenosis rates in the region. This article explores the underlying mechanisms and clinical implications of dietary interventions in preventing coronary recoil, highlighting the need for broader recognition and further research into this promising adjunctive therapy.
Preventing coronary artery recoil following DCB angioplasty is crucial to ensure optimal vessel patency and achieve the best clinical outcomes. Here are strategies commonly employed:
Adequate lesion preparation [19-21];
Proper balloon sizing and inflation [20,22-23];
Use of DCBs with effective drug formulation [24-27];
Imaging guidance [28-31];
Adjunctive pharmacological therapy [32-34];
Meticulous technique [10,35-37];
Avoidance of overstretching [38-40];
Combination strategies [41-45];
Post-procedural medical management [46-48];
atient’s mood stabilization [49-51];
The vasodilatory effect of dietary interventions is primarily mediated through NO, a potent endogenous vasodilator that plays a crucial role in maintaining vascular health. Leafy greens and beets contain nitrates, converted in vivo to NO, relaxing coronary arteries and reducing vasospasm and recoil risk. Garlic's active compound allicin further augments endothelial NO production. Similarly, polyphenols in dark chocolate, berries, and pomegranates significantly enhance endothelial function, stabilize arterial walls, and reduce oxidative stress, contributing directly to minimizing recoil. Citrulline from watermelon is converted to arginine, a precursor to NO, bolstering arterial dilation. Curcumin in turmeric and catechins in green tea also potentiate NO synthesis, providing additional vascular protective effects. Please refer to table 1.

| FOOD | Examples and Active Components | Vascular Effects or Mechanism |
| Leafy Green Vegetables | Spinach, kale, Swiss chard (rich in nitrates) | Nitrates are converted into NO, a potent vasodilator. |
| Beets | High nitrate content | Enhancing NO production causes vasodilation and improves endothelial function. |
| Garlic | Allicin and Sulphur compounds | Increases endothelial NO production and reduces vascular resistance |
| Dark Chocolate/ Cocoa | Flavonoids (epicatechin) | Increase NO bioavailability |
| Berries | Strawberries, blueberries, raspberries. Active compounds: anthocyanins and flavonoids | Boosts NO synthesis, reduces arterial stiffness, and improves endothelial function |
| Pomegranates | Rich in antioxidants and polyphenols | Stimulates NO production, leading to vasodilatation and reducing vascular inflammation. |
| Watermelon | Citrulline is converted to arginine | Enhances oxidative stress and supports NO production, resulting in vasodilatation |
| Turmeric | Curcumin | Enhances endothelial function, reduces oxidative stress, supports NO production, resulting in vasodilatation |
| Green Tea | Catechins (epigallocatechin gallate, EGCG) | Improves endothelial function, increases NO, and reduces vascular inflammation |
| Omega-3 Rich Seeds | Flaxseeds, Chia seeds, hemp seeds | Omega-3 fatty acids support endothelial function and enhance NO availability |
| Citrus Fruits | Oranges, grapefruits, lemons (active component is vitamin C and flavonoids) | Enhances endothelial NO production and improves vascular health |
The integration of these dietary components before angioplasty can condition the endothelium, improve vascular compliance, and mitigate acute elastic recoil, ultimately enhancing short- and long-term procedural outcomes.
At Bethsaida Hospital, under the leadership of Prof. Dasaad Mulijono, we have established a comprehensive, multidisciplinary approach for patients undergoing DCB angioplasty. This includes meticulous lesion preparation employing semi-compliant or non-compliant balloon predilatation and scoring or cutting balloons to enhance lesion compliance and reduce elastic recoil mechanically. Pharmacologically, intracoronary vasodilators, such as nitro-glycerine and calcium channel blockers, are routinely used to minimize vasospasm and reduce the risk of recoil. Additionally, we integrate advanced imaging techniques, including IVUS and OCT, to optimize balloon sizing, lesion assessment, and plaque modification.
Crucially, our approach emphasizes dietary interventions with a structured WFPBD regimen initiated before the procedure. This dietary preparation has significantly contributed to a marked reduction in acute recoil episodes compared to patients maintaining conventional diets. Remarkably, this holistic approach has yielded a restenosis rate of as low as 2%, one of the lowest rates recorded nationally. Although these clinical outcomes are highly encouraging, further comprehensive and controlled studies are necessary to solidify and expand upon these findings.
Prioritizing dietary interventions as part of the preparation for DCB angioplasty has the potential to transform procedural outcomes. A carefully structured pre-procedural diet incorporating nitrate-rich vegetables, polyphenol-dense fruits, omega-3 seeds, and antioxidant-rich teas can significantly reduce recoil events. Coupled with traditional procedural techniques such as adequate lesion preparation and optimal balloon sizing, dietary approaches provide a comprehensive strategy to enhance clinical results.
Despite growing scientific support for Whole-Food Plant-Based Diets (WFPBDs) in preventing and reversing chronic diseases, several limitations and barriers hinder their widespread adoption. Culturally, many populations—especially in meat-centric societies—associate health and status with animal-based foods, making the transition to a plant-based lifestyle a socially challenging endeavor. Economically, although plant-based staples like legumes and grains are affordable, the perception that healthy plant-based eating is expensive persists, primarily when influenced by commercialized vegan products. Knowledge gaps among healthcare providers further exacerbate the problem, as most medical education lacks robust training in nutrition, leading to limited guidance and support for patients. Additionally, psychological dependence on comfort foods and emotional eating often ties individuals to high-fat, sugary, or animal-derived meals. Accessibility to diverse and appealing plant-based options remains another hurdle in regions with limited availability or culinary innovation. Lastly, misinformation propagated through media, industry lobbying, or anecdotal counterexamples can distort public perception, delaying acceptance and trust in evidence-based plant-based nutrition. Overcoming these barriers requires systemic education, supportive environments, and culturally sensitive approaches [52-55].
Dietary interventions rich in vasodilatory and antioxidant-rich foods represent a vital yet underrecognized strategy in interventional cardiology, particularly in preventing coronary recoil post-DCB angioplasty. Bethsaida Hospital's experience demonstrates the substantial benefits achievable by integrating a meticulously structured WFPBD regimen alongside advanced mechanical and pharmacological approaches. Such holistic interventions can significantly reduce acute recoil events, substantially lower restenosis rates, and improve overall vessel patency and patient outcomes. Encouraging broader adoption of these comprehensive dietary strategies within the cardiovascular community is essential. Further rigorous, controlled studies are warranted to conclusively validate these promising results and facilitate the integration of nutritional interventions as standard practice in angioplasty procedures, reinforcing the critical importance of lifestyle medicine in cardiovascular care.
