In research on Type A personality and cardiovascular disease, individuals who suppress and hold their emotions inside have higher early heart attack mortality compared to those who express emotions outwardly.
"that original typing of people who tend to die early from heart attack, it was the people who hold it inside. It was about people who who manage a lot, do a lot, but hold inside. And it's kind of interesting because the ones that turned out, and I'm not suggesting people do that, screamed and yelled a lot. That that catharsis actually helped them in terms of longevity."

The speaker conflates the original 'Type A' behavioral concept with subsequent research on anger coping ('anger-in' vs. 'anger-out') and 'Type D' (distressed/inhibited) personality. The original Type A pattern described by Friedman and Rosenman was characterized by outward competitiveness, time urgency, and hostility, rather than emotional suppression. Prospective observational studies, such as the Tecumseh Community Health Study (PMID 3728438) and CAD cohort studies (PMID 20494661), did find that suppressing anger ('anger-in') was associated with higher all-cause mortality (OR 1.7–2.0) and cardiac events (OR 2.87 for cardiac death/MI) compared to outward anger expression. However, claiming that outward screaming and yelling ('catharsis') promotes longevity overstates the findings, as explosive anger and hostility are well-established acute triggers and risk factors for adverse cardiovascular events.

"However, suppressed anger remained associated with the more rigorous end point of cardiac death or myocardial infarction (odds ratio 2.87, 95% confidence interval 1.15 to 7.15, p = 0.024) after controlling for decreased systolic function, poor exercise tolerance, extent of CAD, and revascularization."

"Subjects who indicated that they were likely to suppress their anger in response to two hypothetical anger-provoking situations had 1.7 times the mortality risk of those who expressed their anger (95% confidence interval (CI) = 1.03-3.05). Subjects who suppressed their anger when unjustifiably confronted by their spouse had twice the mortality risk of those who expressed their anger (95% CI = 1.13-3.38)."
