Real-world effectiveness of blood thinners
Emulation of ARISTOTLE and ROCKET AF trials in real-world atrial fibrillation patients results in similar efficacy and safety as original landmark trials: insights from the GARFIELD-AF registry.
We explored how well the outcomes of landmark trials for two blood thinners—apixaban and rivaroxaban—hold up in real-world atrial fibrillation (AF) patients. By examining data from the GARFIELD-AF registry, we found that patients on these treatments had similar results in preventing strokes, bleeding, and overall mortality when compared to those on vitamin K antagonists.
While apixaban showed promising results, rivaroxaban had more mixed findings, yet overall, the effectiveness and safety were largely in line with the original trials. This suggests that these medications can be appropriately used in everyday medical practice.

Vitamin K antagonists raise mortality risk
Direct Oral Anticoagulants Versus Vitamin K Antagonists After Mitral Valve Transcatheter Edge-to-Edge Repair in Patients With Atrial Fibrillation: A Single-Center Observational Study.
We analyzed data from a study involving patients who underwent mitral valve repair and had atrial fibrillation, comparing the effects of direct oral anticoagulants to vitamin K antagonists (VKAs).
Surprisingly, we found that both treatments led to similar rates of serious complications, like strokes or bleeding. However, those on VKAs showed a significantly higher overall mortality. This suggests that while both anticoagulants may work similarly for immediate outcomes, VKAs might come with increased risks for longer-term survival. Further research is needed to clarify the best options for these patients.

DOACs outperform VKAs post-LAAC
Left atrial appendage closure in patients with failure of anticoagulation therapy: A multicenter comparative study on the hybrid strategy using DOACs and VKAs.
We analyzed a study comparing two anticoagulation options—direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs)—in patients with non-valvular atrial fibrillation who faced blood clots despite previous treatment.
Our findings reveal that those on DOACs had significantly fewer cardioembolic events and complications following left atrial appendage closure.
In contrast, patients on VKAs did not show the same benefit, which suggests that DOACs may be a more effective option for ongoing treatment in these cases.

Cardiovascular protection
1 people found this helpful
This Vitamin K2 is excellent for the cardiovascular system. It redistributes calcium, clearing it from arteries, thus protecting against heart disease.
Heart disease refers to a range of conditions that affect the heart's function and overall health. This umbrella term includes various cardiovascular issues such as coronary artery disease, which is caused by the buildup of plaque in the arteries; heart rhythm problems (arrhythmias); and heart defects present at birth (congenital heart defects). Additionally, heart disease encompasses conditions related to the heart muscle, such as cardiomyopathy, and the heart's valves, which might not open or close properly. The effects of heart disease can be significant, impacting not only physical health but also quality of life, making prevention and timely medical intervention crucial.
Several risk factors contribute to the development of heart disease, including high blood pressure, high cholesterol levels, diabetes, obesity, poor diet, physical inactivity, and smoking. Genetics also play a role, as heart disease can run in families. To mitigate the risks, healthcare professionals typically recommend lifestyle changes such as adopting a heart-healthy diet, engaging in regular physical activity, and avoiding tobacco use. For those already diagnosed with heart disease, treatment options can vary widely, ranging from lifestyle modifications to medications and, in severe cases, surgical interventions. Understanding the nature of heart disease and its risk factors is an essential step toward prevention and effective management.
Vitamin K is a fat-soluble vitamin crucial for various bodily functions, particularly in the clotting process of blood. It exists in two primary forms: K1 (phylloquinone), which is primarily found in leafy green vegetables like spinach and kale, and K2 (menaquinone), which is found in fermented foods and certain animal products. Vitamin K plays a significant role in the synthesis of proteins that regulate blood coagulation and is also essential for bone metabolism, assisting in the binding of calcium to bones and other tissues.
Deficiencies in vitamin K can lead to increased bleeding and bruising, and in severe cases, it may contribute to bone weakness. While most people can obtain adequate amounts of vitamin K through a balanced diet rich in vegetables and fermented foods, those with certain medical conditions or who are on specific medications may require monitoring and supplementation. Incorporating a variety of nutrient-dense foods into your diet is the best way to ensure you get enough vitamin K for optimal health.
Recent studies suggest that Vitamin K may play a beneficial role in heart health, primarily due to its involvement in the regulation of calcium in the arteries. Vitamin K helps activate proteins that prevent calcium buildup in the arteries, which is a significant risk factor for heart disease. Some research has indicated that higher intake of vitamin K might be associated with a lower risk of cardiovascular disease, although the evidence is still emerging and further studies are needed to establish a definitive link.
However, while Vitamin K can contribute to cardiovascular health, it is not a standalone solution for heart disease prevention or management. A well-rounded approach, including a balanced diet rich in fruits, vegetables, whole grains, and healthy fats, regular physical activity, and other lifestyle modifications, should be your primary strategy. As always, consult with healthcare professionals before making any significant changes to your diet or supplement regimen.
Based on user reviews, it can take anywhere from a few weeks to several months to see the benefits of taking Vitamin K2, particularly in relation to heart health. For instance, one user reported significant improvement in their dental and periodontal health after two months of consistent use, attributing their heart health advantages to the same supplement Read Review. Another user mentioned a four-month duration of use, emphasizing its role in heart disease health and calcium distribution Read Review.
Moreover, regular intake of K2 has been noted to significantly enhance cardiovascular functions and improve overall well-being, suggesting that longer-term commitment may yield more pronounced results Read Review. While user experiences vary, most agree that patience is key, as the benefits accumulate over time, making K2 a worthwhile addition to a heart health regimen.
The research surrounding vitamin K and its impact on heart disease presents a mixed bag of findings. A study investigating vitamin K antagonists (VKAs) in patients with atrial fibrillation found no significant improvement in heart disease directly attributable to vitamin K treatment. Instead, outcomes were more influenced by factors like age and kidney function [1]. Another study focused on the effects of VKAs after mitral valve repair found that while VKAs and direct oral anticoagulants had similar immediate outcomes, VKAs were associated with a higher overall mortality rate, raising concerns about their longer-term safety [2].
On a more positive note, research on vitamin K1 specifically indicates that it may help manage heart health, particularly in patients undergoing hemodialysis. In a study, vitamin K1 significantly slowed the progression of coronary artery calcifications in this population by 55%, suggesting it may offer heart health benefits in some contexts [5]. However, these benefits must be weighed against the risks identified with using VKAs. Overall, while there is evidence for specific benefits of vitamin K1, the general consensus on VKAs in the context of heart disease suggests a cautious approach, highlighting the need for further studies to clarify their role in heart health.

Furthermore, many reviews highlight the long-term benefits of taking Vitamin K2, with regular users experiencing sustained health improvements over several months. One user reported feeling more robust in heart health after just a few weeks of use, while another noted enhanced benefits in maintaining vascular integrity and preventing osteoporosis Read Review. Although individual results can vary, the overarching sentiment among reviewers is that Vitamin K2 is a worthwhile supplement for anyone looking to bolster their heart health and dental well-being.
Users report that combining Vitamin K2 with other supplements, particularly Vitamin D3, can significantly enhance cardiovascular health and help prevent heart disease. Many reviewers have emphasized the importance of this combination, citing that Vitamin K2 aids in regulating calcium levels in the body, directing calcium to the bones instead of allowing it to accumulate in arteries. For instance, one user noted that they prefer taking Vitamin K2 and D3 from separate jars for optimal health benefits, highlighting its role in preventing vascular calcification Read Review. Another user emphasized that this duo not only supports heart health but also improves dental conditions, demonstrating a broad range of health benefits Read Review.
Additionally, many reviewers have mentioned that consistent use of Vitamin K2 in conjunction with Vitamin D results in improved calcium absorption and distribution, which are vital for maintaining both bone and cardiovascular health. Users describe feeling more robust and seeing significant improvements in their health scores when they incorporate this supplement combination into their daily regimen Read ReviewRead Review. Overall, the consensus among users is that combining Vitamin K2 with Vitamin D is a powerful strategy for those looking to enhance their heart health.
Based on user reviews, Vitamin K2 has been consistently highlighted for its role in promoting heart health by regulating calcium metabolism in the body. Users recommend combining it with Vitamin D3 for enhanced efficacy, noting that K2 helps direct calcium to the bones rather than allowing it to accumulate in blood vessels, which can decrease the risk of heart disease (Read Review). Many users report that daily supplementation—often in the MK-7 form—is crucial for this purpose, emphasizing its effectiveness in preventing vascular calcification (Read Review).
Several reviews also point out that appropriate dosing of K2 can lead to significant improvements in cardiovascular health and bone strength. For example, a user mentioned that their overall heart health felt greatly enhanced after regular use of K2 (Read Review). Additionally, there are indications that higher doses of Vitamin K2 correspond to lower risks of coronary heart disease, with some users believing that supplementation could be life-extending (Read Review). However, specific dosage recommendations were not explicitly detailed in the reviews.
