Summary
A multicenter randomized trial (HERMeS) showed that mHealth combining telemonitoring and structured teleintervention cut cardiovascular events by 65% in recently discharged heart failure patients.

A systematic review/meta-analysis confirmed low-dose colchicine reduces non-fatal ischemic events in ASCVD without affecting mortality.
Research Themes
- Digital health and telemonitoring in heart failure transitional care
- Inflammation-targeting therapies in ASCVD (colchicine)
- Vascular biology mechanisms in aortic disease (NPR-C, mitochondrial homeostasis)
Selected Articles
1. Evaluation of mobile health technology combining telemonitoring and teleintervention versus usual care in vulnerable-phase heart failure management (HERMeS): a multicentre, randomised controlled trial.
In the HERMeS phase 3 trial of 506 recently discharged heart failure patients, a telemonitoring plus structured teleintervention program reduced the composite of cardiovascular death or worsening heart failure versus usual care (HR 0.35). Benefits were observed over 6 months without reported safety signals. Findings support integrating mHealth into transitional HF care.
Impact: First robust RCT to demonstrate event reduction using combined telemonitoring and teleintervention during the vulnerable post-discharge phase of heart failure.
Clinical Implications: Supports routine integration of telemonitoring plus structured remote follow-up in early post-discharge HF pathways to reduce cardiovascular death and decompensation.
Key Findings
- Composite of cardiovascular death or worsening heart failure reduced with mHealth vs usual care (17% vs 41%; HR 0.35, 95% CI 0.24–0.50).
- Randomized 1:1, 506 adults post HF decompensation; follow-up 24 weeks.
- No spontaneously reported harms; consistent benefit across the vulnerable phase.
Methodological Strengths
- Multicenter randomized controlled design with masked endpoint adjudication
- Clear primary composite endpoint and intention-to-treat analysis
Limitations
- Open-label design could introduce behavioral or care biases
- Conducted within one country’s health system, which may affect generalizability
Future Directions: Validate across diverse healthcare systems, assess cost-effectiveness, and delineate which teleintervention components drive the effect.
2. Deficiency of NPR-C triggers high salt-induced thoracic aortic dissection by impairing mitochondrial homeostasis.
This translational study identifies NPR-C as a protective regulator against high-salt–triggered thoracic aortic dissection via mitochondrial fatty acid oxidation in vascular smooth muscle. VSMC-specific NPR-C loss enabled TAD with AngII+high salt, downregulating MTP component HADHB through ERK1/2–PPARγ signaling. NPR-C agonism and spermidine prevented or mitigated TAD in vivo.
Impact: Reveals a novel NPR-C–mitochondrial FAO axis in TAD pathogenesis with actionable targets (NPR-C agonist, spermidine), bridging human omics and in vivo models.
Clinical Implications: Suggests NPR-C activation and spermidine as candidate preventive/therapeutic strategies for salt-sensitive aortic disease; highlights dietary salt as a modifiable trigger.
Key Findings
- VSMC-specific NPR-C knockout mice developed TAD with AngII plus high-salt diet, not with AngII alone.
- NPR-C loss reduced mitochondrial FAO gene expression (notably HADHB) via ERK1/2 activation and PPARγ suppression.
- NPR-C agonist (C-ANP4-23) mitigated TAD progression; spermidine (MTP activator) prevented TAD formation.
Methodological Strengths
- Integrated human transcriptome/single-cell analyses with multiple in vivo mechanistic models
- Genetic cell type–specific knockouts and pharmacologic rescue experiments
Limitations
- Preclinical murine models may not fully recapitulate human TAD complexity
- Therapeutic doses/translation of spermidine and NPR-C agonists require further safety/PK studies
Future Directions: Evaluate NPR-C agonists and spermidine in large-animal models and early-phase clinical trials; define patient subsets with NPR-C downregulation and salt sensitivity.
3. The efficacy and safety of low dose colchicine in atherosclerotic cardiovascular disease - A systematic review and meta-analysis.
Across 11 RCTs (n=30,808), low-dose colchicine reduced MACE by 17% and extended MACE by 23%, driven by reductions in myocardial infarction and coronary revascularization; stroke reduction was non-significant and there was no effect on cardiovascular or non-cardiovascular mortality. Safety signals were not increased.
Impact: Provides contemporary synthesis reaffirming anti-ischemic benefits of colchicine in ASCVD despite heterogeneous trial results, supporting guideline uptake while clarifying absence of mortality benefit.
Clinical Implications: Supports low-dose colchicine to reduce non-fatal ischemic events in chronic ASCVD, with counseling that survival is not improved; patient selection and drug–drug interaction monitoring remain essential.
Key Findings
- Colchicine reduced MACE (RR 0.83, 95% CI 0.73–0.95; p=0.006) and extended MACE (RR 0.77, 95% CI 0.63–0.94; p=0.01).
- Benefits driven by fewer myocardial infarctions (RR 0.78) and coronary revascularizations (RR 0.73); stroke reduction NS.
- No effect on cardiovascular (RR 0.96) or non-cardiovascular mortality (RR 1.04).
Methodological Strengths
- Pre-registered (PROSPERO) systematic search and random-effects meta-analysis
- Large aggregate sample (30,808) with clinically relevant endpoints
Limitations
- Heterogeneity across trials in populations, dosing, and background therapies
- Mortality-neutral signal limits impact on survival-focused outcomes
Future Directions: Define subgroups most likely to benefit (e.g., residual inflammatory risk), optimize dose/duration, and assess integration with contemporary lipid- and anti-thrombotic therapies.
