European Heart Journal Submission Guide: Requirements & Editor Tips

European Heart Journal enforces strict formatting standards that editors check before sending papers to review. Your manuscript gets desk-rejected if these requirements aren't met exactly.

Word Limits by Article Type:

• Original Articles: 4,000 words maximum (excluding references and figure legends)
• Review Articles: 6,000 words maximum
• Rapid Communications: 2,500 words maximum
• Editorials: 1,500 words maximum

Abstract Structure:

Clinical research papers require structured abstracts with these exact headings: Aims, Methods and Results, Conclusions. Basic science papers use: Aims, Methods and Results, Conclusions. Keep abstracts under 250 words. Don't include citations in abstracts.

Reference Format:

Use Vancouver style with DOIs for all references when available. Limit references to 50 for original articles, 150 for reviews. Journal abbreviations follow Index Medicus standards. Recent references (within 5 years) should comprise at least 60% of your citations.

Figure Specifications:

Submit figures as separate files in TIFF or EPS format, minimum 300 DPI resolution. Color figures are allowed but must be meaningful (not decorative). Each figure needs a detailed legend explaining all abbreviations and symbols. Maximum 8 figures for original articles.

Statistical Requirements:

Report confidence intervals for all main outcomes. Use appropriate statistical tests for your data type. Include power calculations for negative studies. Prespecify all statistical analyses in your methods section. The journal requires raw P-values, not just "P < 0.05."

European Regulatory Compliance:

Include ethics approval numbers for all human studies. Reference relevant European medicines regulations. Cite applicable ESC guidelines in your discussion. International studies must explain European regulatory context.

Technical Details:

Double-space everything, including references. Use Times New Roman 12-point font. Number all pages. Include line numbers for easy reviewer reference. Submit a separate title page with author details to facilitate blinded review.

Your European Heart Journal cover letter needs to emphasize European relevance immediately. Editors want to see why European cardiologists should care about your findings.

Opening Paragraph Structure:

State your manuscript title, article type, and European connection in the first sentence. Mention relevant European populations, registries, or guidelines. Don't waste space on generic journal praise. Get straight to why this matters for European cardiovascular practice.

Example opening: "We submit our original research article 'Long-term Outcomes in European Heart Failure Patients: Results from the ESC-HF Long-Term Registry' for publication in European Heart Journal. This analysis of 15,847 heart failure patients across 21 European countries provides the largest real-world evidence base for ESC guideline recommendations on heart failure management."

European Scope Emphasis:

Explicitly connect your findings to ESC guidelines, European regulatory decisions, or European clinical practice patterns. Mention how your results might influence future ESC position papers or treatment recommendations. Reference European patient populations, healthcare systems, or regulatory frameworks.

Methodological Strengths:

Highlight statistical power, study design rigor, or methodological innovations. European Heart Journal editors prioritize methodologically sound research. Mention if your study addresses previous European research gaps or confirms findings in European populations.

Practice Implications:

Explain how your findings could change European cardiovascular practice. Will this influence ESC guideline updates? Does it support or challenge current European treatment approaches? Be specific about clinical implications for European cardiologists.

Keep your cover letter under 400 words. End with a brief statement about author contributions and funding sources. Don't repeat your abstract contents. The cover letter should convince editors that European cardiologists need to read this research.

These submission errors lead to immediate desk rejection at European Heart Journal. Most are preventable with careful preparation.

Single-Center Studies Without Justification:

The fastest way to desk rejection is submitting single-institution research without compelling methodological reasons. Editors reject 90% of single-center observational studies immediately. Exceptions include novel surgical techniques, rare disease series, or methodological innovations that require specific institutional expertise. Your cover letter must justify why single-center data matters for European cardiovascular practice.

Ignoring European Context:

Papers that don't acknowledge European cardiovascular epidemiology, guidelines, or healthcare systems get rejected. You can't submit a U.S. registry study without discussing European relevance. Even basic science papers need European clinical context. Reference ESC guidelines, European regulatory decisions, or European patient populations in your discussion.

Inadequate Statistical Power:

Underpowered negative studies get rejected unless they're pilot studies or proof-of-concept research. Calculate and report statistical power for your primary outcomes. For cardiovascular endpoints, editors expect power calculations based on realistic effect sizes. Don't submit exploratory analyses of existing datasets without appropriate multiple comparison adjustments.

Poor Integration with Existing Evidence:

Papers that ignore relevant European cardiovascular literature get desk-rejected. Your systematic literature review must include major European studies, ESC guideline references, and relevant European registry data. Editors want to see how your findings fit into existing European cardiovascular knowledge.

Methodological Shortcuts:

European Heart Journal editors catch statistical errors, inappropriate study designs, and analytical shortcuts. Common problems include: using surrogate endpoints without validation, inadequate confounder adjustment in observational studies, and inappropriate statistical tests for cardiovascular data. Get statistical review before submission.

Weak Clinical Relevance:

Research without clear implications for cardiovascular practice gets rejected regardless of methodological quality. Editors ask: "How does this change what European cardiologists do?" Basic science papers need translational potential. Clinical studies need practice implications. Your discussion must explicitly address clinical relevance.

Before submitting, check whether your paper addresses these common failure points. Our 10 Signs Your Paper Isn't Ready to Submit (Yet) provides additional preparation guidance.

If European Heart Journal isn't right for your cardiovascular research, these alternatives offer different advantages based on your study characteristics and career goals.

Circulation works better for U.S.-focused studies or research without specific European relevance. The American Heart Association's flagship journal has similar prestige but different editorial priorities. Submit here if your study involves primarily North American populations or challenges established AHA/ACC guidelines.

Journal of the American College of Cardiology specializes in interventional cardiology, imaging, and device studies. JACC's multiple subspecialty journals offer targeted audiences. Consider JACC: Heart Failure for heart failure research or JACC: Cardiovascular Interventions for procedural studies.

Circulation Research is the right choice for basic cardiovascular science without immediate clinical applications. If your research focuses on cardiovascular mechanisms, molecular biology, or translational research requiring extensive basic science background, Circulation Research offers better fit than European Heart Journal's clinical focus.

European Journal of Heart Failure serves as a natural step-down option for heart failure research that doesn't meet European Heart Journal's standards. Heart offers broader cardiovascular scope with lower competition. Both maintain strong European editorial boards and clinical focus.

Consider your timeline, career stage, and study limitations when choosing alternatives. Getting published in a well-matched journal beats rejection from a higher-impact journal that doesn't fit your research.
