We know that B12 deficiency contributes to heart disease
by raising homocysteine levels, but that is easily preventable
by taking a B12 supplement. (Not the fault of the diet per -
se, but destructive modern agricultural and medical practices)

Otherwise;

'Plasma lipids and diet groups

The first article published about this study compared concentrations
of total cholesterol and various lipoprotein fractions in 4 diet groups:
vegans, who never ate animal products; vegetarians, who never ate
meat or fish but did eat dairy products, eggs, or both; fish eaters, who
ate fish but no meat; and meat eaters (4). Both total- and LDL-cholesterol
concentrations were significantly lower in vegans than in meat eaters,
whereas vegetarians and fish eaters had similar, intermediate values.
HDL-cholesterol concentrations were highest in fish eaters but did not
differ among the other diet groups. Mean cholesterol concentrations for
vegans, vegetarians, fish eaters, and meat eaters, adjusted for age and
sex, are shown in Table 1. On the basis of these results, it was predicted
that the incidence of ischemic heart disease might be 24% lower in
lifelong vegetarians and 57% lower in lifelong vegans than in meat
eaters.
....
The most striking results from the analysis were the strong positive
associations between increasing consumption of animal fats and ischemic
heart disease mortality [death rate ratios (and 95% CIs) for the highest
third of intake compared with the lowest third in subjects with no prior
disease were 3.29 (1.50, 7.21) for total animal fat, 2.77 (1.25, 6.13)
for saturated animal fat, and 3.53 (1.57, 7.96) for dietary cholesterol;
P for trend: <0.01, <0.01, and <0.001, respectively]. In contrast, no
protective effects were noted for dietary fiber, fish, or alcohol consumption.
Consumption of eggs and cheese were both positively associated with
ischemic heart disease mortality in these subjects (P for trend, < 0.01 for
both foods).

Those findings are at odds with other, more detailed studies.

Am J Clin Nutr 1999 Sep;70(3 Suppl):532S-538S
Associations between diet and cancer, ischemic heart disease,
and all-cause mortality in non-Hispanic white California
Seventh-day Adventists.
Fraser GE. Center for Health Research and the Department of
Epidemiology and Biostatistics, Loma Linda University, CA USA.
 Results associating diet with chronic disease in a cohort of 34192
California Seventh-day Adventists are summarized. Most Seventh-day
Adventists do not smoke cigarettes or drink alcohol, and there is a wide
range of dietary exposures within the population. About 50% of those
studied ate meat products <1 time/wk or not at all, and vegetarians
consumed more tomatoes, legumes, nuts, and fruit, but less coffee,
doughnuts, and eggs than did nonvegetarians. Multivariate analyses
showed significant associations between beef consumption and fatal
ischemic heart disease (IHD) in men [relative risk (RR) = 2.31 for
subjects who ate beef > or =3 times/wk compared with vegetarians],
significant protective associations between nut consumption and fatal
and nonfatal IHD in both sexes (RR approximately 0.5 for subjects
who ate nuts > or =5 times/wk compared with those who ate nuts
<1 time/wk), and reduced risk of IHD in subjects preferring whole-grain
to white bread. The lifetime risk of IHD was reduced by approximately
31% in those who consumed nuts frequently and by 37% in male
vegetarians compared with nonvegetarians. Cancers of the colon and
prostate were significantly more likely in nonvegetarians (RR of 1.88
and 1.54, respectively), and frequent beef consumers also had higher
risk of bladder cancer. Intake of legumes was negatively associated
with risk of colon cancer in nonvegetarians and risk of pancreatic
cancer. Higher consumption of all fruit or dried fruit was associated
with lower risks of lung, prostate, and pancreatic cancers.
Cross-sectional data suggest vegetarian Seventh-day Adventists have
lower risks of diabetes mellitus, hypertension, and arthritis than
nonvegetarians. Thus, among Seventh-day Adventists, vegetarians are
healthier than nonvegetarians but this cannot be ascribed only to the
absence of meat.

Speak for yourself, ditch.

Animal product consumption and mortality because of all
causes combined, coronary heart disease, stroke, diabetes,
and cancer in Seventh-day Adventists.
Snowdon DA.
Division of Epidemiology, School of Public Health, University
of Minnesota, Minneapolis.
This report reviews, contrasts, and illustrates previously published
findings from a cohort of 27,529 California Seventh-day Adventist
adults who completed questionnaires in 1960 and were followed
for mortality between 1960 and 1980. Within this population, meat
consumption was positively associated with mortality because of all
causes of death combined (in males), coronary heart disease (in
males and females), and diabetes (in males). Egg consumption was
positively associated with mortality because of all causes combined
(in females), coronary heart disease (in females), and cancers of the
colon (in males and females combined) and ovary. Milk consumption
was positively associated with only prostate cancer mortality, and
cheese consumption did not have a clear relationship with any cause
of death. The consumption of meat, eggs, milk, and cheese did not
have negative associations with any of the causes of death investigated.
