No idea if this could be similar for brain arteries. Ask your doctor what inversely means.
Associations between coffee, tea, and caffeine intake with coronary artery calcification and cardiovascular events

PE, et al. – Researchers conducted this study to determine the
relationship between coffee, tea, and caffeine intake with coronary
artery calcification and cardiovascular events. This study concluded
that moderate tea drinkers had a slower progression of coronary artery
calcium and diminished risk of cardiovascular events.
Methods
- 6,508 ethnically-diverse participants were examined with available coffee and tea data from the Multi-Ethnic Study of Atherosclerosis.
- Admission for each was classified as never, occasional (<1 cup/day), and regular (≥1 cup/day).
- A coronary artery calcium progression ratio was derived from mixed effect regression models using loge(calcium score+1) as the outcome with coefficients exponentiated to reflect coronary artery calcium progression ratio vs. the reference.
- To assess the relationship between beverage intake and incident cardiovascular events, Cox proportional hazards analyses were used.
Results
- Researchers found that over a median follow-up of 5.3 years for coronary artery calcium and 11.1 years for cardiovascular events, participants who regularly drank tea (≥1 cup/day) had a slower progression of coronary artery calcium compared with never drinkers after multivariable adjustment.
- This connected with a statistically significant lower incidence of cardiovascular events for ≥1 cup/day tea drinkers (adjusted HR 0.71; 95% CI 0.53-0.95).
- Contrasted with never coffee drinkers, regular coffee intake (≥1 cup/day) was not statistically connected with coronary artery calcium progression or cardiovascular events (adjusted HR 0.97 [0.78, 1.20]).
- According to the findings obtained, caffeine intake was marginally inversely connected with coronary artery calcium progression.
