As heart disease continues to be the number-one killer in the United States, researchers
have become increasingly interested in identifying the potential risk factors that trigger
heart attacks. High-fat diets and “life in the fast lane” have long been known to contribute
to the high incidence of heart failure. But according to new studies, the list of risk factors
may be significantly longer and quite surprising.
Heart failure, for example, appears to have seasonal and temporal patterns. A higher
percentage of heart attacks occur in cold weather, and more people experience heart
failure on Monday than on any other day of the week. In addition, people are more
susceptible to heart attacks in the first few hours after waking. Cardiologists first observed
this morning phenomenon in the mid-1980, and have since discovered a number of
possible causes. An early-morning rise in blood pressure, heart rate, and concentration of
heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute
to the higher incidence of heart attacks between the hours of 8:00 A.M. and 10:00 A.M.
In other studies, both birthdays and bachelorhood have been implicated as risk factors.
Statistics reveal that heart attack rates increase significantly for both females and males in
the few days immediately preceding and following their birthdays. And unmarried men
are more at risk for heart attacks than their married counterparts. Though stress is thought
to be linked in some ways to all of the aforementioned risk factors, intense research
continues in the hope of further comprehending why and how heart failure is triggered.
