Cardiovascular care studies test treatments, pathways, and risk management for heart disease and related outcomes.

Cardiology claims move fast; these papers anchor what controlled and observational evidence actually shows.

Evidence

What the evidence shows

Drawn from 8 studies in this library. Each finding starts with a plain-language takeaway, then the denser detail. Supports means evidence for a finding; Challenges means evidence against a stated position; Qualifies marks scope with a short note on each study’s contribution. Challenged positions are labeled — they are not findings.

• Multiple studies in this library examine cardiovascular care with empirical patient or population outcomes rather than opinion alone.

• ITT primary events 17% tele vs 33% control (RRR 50%, P=.06); per-protocol RRR 54% (P=.04); NYHA improved only in tele group; HF hospital stays shorter (median 6.5 vs 10 days).

  1. 1Phone telemonitoring after heart-failure flare

• Potential prevention remained roughly one quarter to one third of cases and had not declined between cohorts spanning about two decades, motivating public-health action.

  1. 1How much dementia could prevention still avert?

• Mortality associated with increasing age, male sex, Black vs white race, prior MI, heart failure, dementia, chronic lung, liver, and renal disease, and metastatic solid tumour; common comorbidities included COPD and diabetes.

  1. 1COVID-19 death risk and comorbidities

• Observationally, each 4 kg/m² BMI related to about 26% higher IHD odds; the causal instrumental-variable OR was about 1.52 (52% higher). Alleles raised BMI by ~0.28 kg/m² each.

  1 study
  1. 1Does higher BMI causally raise heart disease risk?

• Each additional 10 g/day olive oil associated with 13% lower major CVD events (HR 0.87) and 16% lower CV mortality (HR 0.84).

Common misconceptions

• ✗Cardiovascular Care findings always generalise to every clinic.

  ✓These studies are context-bound; designs, populations, and endpoints limit transfer.

The studies

8 studies in this library bear on Cardiovascular Care, ordered by citations.

• COVID-19 death risk and comorbidities

  In 31,461 US adults with COVID-19, older age, male sex, Black race, and several comorbidities including heart disease predicted higher mortality.

  PLoS medicine · 2020 · 327 citations

• OSA severity and cardiovascular risk

  In >10,000 sleep-study patients, higher apnea–hypopnea burden predicted cardiovascular events and death over years of follow-up.

  PLoS medicine · 2014 · 311 citations

• Does higher BMI causally raise heart disease risk?

  Genetic instruments for BMI suggest a causal increase in ischemic heart disease risk larger than simple observational estimates.

  PLoS medicine · 2012 · 231 citations

• Literacy-friendly HF self-care trial

  A literacy-sensitive outpatient heart failure education program improved knowledge and self-efficacy but did not clearly cut hospitalizations or quality-of-life scores versus usual care.

  BMC health services research · 2006 · 231 citations

• Olive oil intake and CVD risk

  Higher olive oil intake tracked lower major CVD events and cardiovascular death in PREDIMED participants.

  BMC medicine · 2014 · 228 citations

• How much dementia could prevention still avert?

  In Rotterdam cohorts, about one quarter to one third of dementia cases were potentially attributable to modifiable risks—and that share did not shrink over two decades.

  BMC medicine · 2015 · 214 citations

• How broadly does smoking raise heart and vessel disease risk?

  In a large Australian cohort, current smoking raised risk across nearly all CVD subtypes—especially peripheral arterial disease—and quitting lowered risk.

  BMC medicine · 2019 · 198 citations

• Phone telemonitoring after heart-failure flare

  Home mobile-phone telemonitoring after acute heart-failure decompensation cut primary events and hospital days versus usual care.
